# Korean shamanism

Korean shamanism, also known as musok (Korean: 무속; Hanja: 巫俗) or Mu-ism (무교; 巫敎; Mugyo), is a religion from Korea. Scholars of religion classify it as a folk religion and sometimes regard it as one facet of a broader Korean vernacular religion distinct from Buddhism, Daoism, and Confucianism. There is no central authority in control of musok, with much diversity of belief and practice evident among practitioners.
A polytheistic religion, musok revolves around deities and ancestral spirits. Central to the tradition are ritual specialists, the majority of them female, called mudang (무당; 巫堂) or mu (무; 巫). In English they have sometimes been called "shamans", although the accuracy of this term is debated among anthropologists. The mudang serve as mediators between paying clients and the supernatural world, employing divination to determine the cause of their clients' misfortune. They also perform gut rituals, during which they offer food and drink to the gods and spirits or entertain them with storytelling, song, and dance. Gut may take place in a private home or in a guttang shrine, often located on a mountain. The mudang divide into regional sub-types, the largest being the mansin or kangsin-mu, historically dominant in Korea's northern regions, whose rituals involve them being personally possessed by deities or ancestral spirits. Another type is the sesŭp-mu of eastern and southern regions, whose rituals entail spirit mediumship but not possession.
Elements of the musok tradition may derive from prehistory. During the Joseon period, Confucian elites suppressed the mudang with taxation and legal restrictions, deeming their rites to be improper. From the late 19th century, modernisers – many of whom were Christian – characterised musok as misin (superstition) and supported its suppression. During the Japanese occupation of the early 20th century, nationalistically oriented folklorists began promoting the idea that musok represented Korea's ancient religion and a manifestation of its national culture; an idea later heavily promoted by mudang themselves. In the mid-20th century, persecution of mudang continued under the Marxist government of North Korea and through the New Community Movement in South Korea. More positive appraisal of the mudang occurred in South Korea from the late 1970s onward, especially as practitioners were associated with the minjung pro-democracy movement and came to be regarded as a source of Korean cultural identity.
Musok is primarily found in South Korea, where there are around 200,000 mudang, although practitioners are also found abroad. While Korean attitudes to religion have historically been fairly inclusive, allowing for syncretism between musok and Buddhism, the mudang have nevertheless long been marginalised. Disapproval of mudang, often regarded as charlatans, remains widespread in South Korea, especially among Christians. Musok has also influenced some Korean new religions, such as Cheondoism and Jeungsanism.

## Definition

The anthropologist Chongho Kim noted that defining Korean shamanism was "really problematic". He characterised "Korean shamanism" as a largely "residual" category into which all Korean religious practices that were not Buddhist, Confucian, or Christian were placed. Scholars like Griffin Dix, Kil-sŏng Ch'oe and Don Baker have conversely presented Korean shamanism as just one facet of "Korean folk religion", the latter sometimes called minsok chonggyo in Korean.
Korean shamanism has varyingly been labelled a vernacular religion, a folk religion, a popular religion, and an indigenous religion. It is a non-institutionalized tradition, rather than being an organized religion akin to Buddhism or Christianity. It has no doctrine, nor any overarching hierarchy, and is orally transmitted. It displays considerable regional variation, as well as variation according to the choices of individual practitioners. Over time, the tradition has displayed both continuity and change.
One term commonly used for this tradition is musok ("mu folklore"), coined by the folklorist Yi Nŭnghwa. Although developed during the Japanese colonial period, when it was employed with derogatory connotations, the term has since become popular with the Korean population and with scholars; the Korean studies scholar Antonetta L. Bruno for instance capitalised it as Musok to serve as a name for the religion. Alternative terms include mugyo, muijŭm, and mu. In Korea, the term misin ("superstition") is sometimes used for this religion, but is also applied to other religious and cultural practices like geomancy. While misin carries negative connotations in Korean culture, some mudang use it to describe what they do.
Since the late 19th century, English language studies have referred to the mudang as "shamans" and their practices as "Korean shamanism", a label rendered into Korean as shyamŏnijŭm. Introduced to English from the Tungusic languages at the end of the 17th century, the term "shamanism" has never received a commonly agreed definition and has been used in at least four distinct ways. A common definition uses "shamanism" to describe traditions involving visionary flights to perform rituals in a spirit realm, a practice not found in Korean traditional religion. Many scholars avoid the term "shaman" as a cross-cultural category altogether. Its application to Korean religion is controversial, with Chongho Kim deeming it "often unhelpful". The scholar Suk-Jay Yim proposed mu-ism as a more appropriate label than "Korean shamanism", while Dix thought "spirit mediumship" more suitable than "shamanism".
Prior to Christianity's arrival in the 17th and 18th centuries, Korean religion was rarely exclusivist, with many Koreans practising Daoism, Buddhism, Confucianism, and musok simultaneously. Despite shared underlying beliefs, these traditions undertook a "division of ritual and cosmological responsibility" between each other. Confucian rituals were for example primarily concerned with ancestor veneration and tended to be simpler and more regular, whereas the mudang would be brought in on rarer occasions. Korea has seen particular syncretism between musok and Buddhism; mudang often identify as Buddhists, and commonly worship Buddhist deities, while some Korean Buddhist temples venerate deities traditionally associated with musok. In contemporary South Korea, it remains possible for followers of most religions (barring Christianity) to involve themselves in musok with little censure from their fellow religionists. Meanwhile, mudang based in Europe have merged the tradition with New Age elements.

### Terms and types of practitioners

Central to musok are those whom the anthropologist Kyoim Yun called "ritual specialists who mediate between their clients and the invisible" forces of the supernatural. The most common Korean term for these specialists is mudang, a label that encompasses various "folk religion practitioners" across the peninsula.
Although commonly used, the term mudang carries derogatory connotations in Korean culture and thus some practitioners avoid it. An alternative term is mu, the latter synonymous with the Chinese word wu (Hanja: 巫), also used for ritual specialists. Several modern mudang advocacy groups have adopted the term musogin, meaning "people who do mu". While the term mudang can apply to a man or woman, specific terms for male musok specialists include paksu, or, more commonly used in the past, kyŏksa. Modern advocacy groups have also described supporters as sindo (believers, Hanja: 信徒) or musindo (believers in the ways of mu, Hanja: 巫信徒).
Mudang are often divided into two broad types: the kangsin-mu, or "god-descended" mu, and the sesŭp-mu or "hereditary" mu. The former engage in rituals in which they describe being possessed by supernatural entities; the latter's rituals involve interaction with these entities but not possession. The former was historically more common in northern and central parts of the Korean peninsula, the latter in southern parts below the Han River. The kangsin-mu tradition later spread and by the late 20th century was dominant across South Korea, with its ritual costumes and paraphernalia being widely adopted.
Lines between the sesŭp-mu and kangsin-mu are nevertheless blurred. Although the sesŭp-mu are typically presented as inheriting the role in a hereditary fashion, not all sesŭp-mu do so, while some kangsin-mu continue the role of a family member as if maintaining a hereditary tradition. Yun commented that dividing the mudang into distinct typologies "cannot explain complex reality".
Certain regional terms are also used for the mudang. The sesŭp-mu are often called tanggol in Jeolla Province, and simbang on Jeju Island. The latter term was first recorded in the 15th century, used for mudang on the Korean mainland, but by the early 19th century was exclusively used for practitioners on Jeju. An alternative term for the kangsin-mu is mansin, a term meaning "ten thousand spirits/gods", and which has less derogatory connotations than the label mudang.
Other terms sometimes used for mudang may elsewhere be restricted to different types of Korean ritual specialist. The term yeongmae, describing a spirit medium, is sometimes used synonymously with mudang but at other times describes a distinct group of practitioners. Another term some mudang adopt for themselves is posal (bosal), originally a Korean term for a Buddhist bodhisattva, and which is favored more by female than male practitioners. Conversely, some mudang maintain that the term posal should be reserved for diviners who are possessed by child spirits but who do not perform the gut rituals of the mudang.

## Beliefs
### Theology

Musok is polytheistic. Supernatural beings are called gwisin, or sin. The mudang divide these beings into two main groups, the gods and the ancestral spirits, although many use the term sin for all of them. Supernatural beings are seen as volatile; if humans do well by them, they can receive good fortune, but if they offend these entities then they may suffer. Devotees of these deities believe that they can engage, converse, and bargain with them.
Each mudang will have their own personal pantheon of deities, one that may differ from the pantheon of the mudang they trained under. This individual pantheon is the chusin, and a mudang may add new deities to it during their career. Some will be considered guardian deities, each referred to as a taesin. These deities bestow myŏnggi ("divine energy") upon the mudang, enabling the latter to have visions and intuition that allows them to perform their ritual tasks.

#### Janggunsin

In Korean traditional religion, the deities are called janggunsin, and typically take human form. The pantheon of deities, which has changed over time, is termed sindang, with over 130 musok divinities having been identified. The deities can be divided into those embodying natural or cosmological forces and those who were once human, including monarchs, officials, and generals. Some derive from Daoist or Buddhist traditions and others are unique to Korean vernacular religion. They are deemed capable of manifesting in material forms, as in paintings or statues, or as inhabiting landscape locations such as trees, rocks, springs, and stone piles. The anthropologist Laurel Kendall suggested that the relationship that mudang had with these spirit-inhabited sites was akin to animism.
The highest deities are often deemed remote and little interested in human affairs. The governing god in Korean tradition, referred to as Hananim, Hanallim, or Hanŭnim, is deemed to rule the heavens but is rarely worshipped. Some of the more powerful deities can make demands from humans without any obligation to reciprocate. Other deities are involved in everyday human concerns and prayed to accordingly. Many of the deities desire food and drink, spend money, and enjoy song and dance, and thus receive these things as offerings. Spirits of the dead are thought to yearn for the activities and pleasures they enjoyed in life; spirits of military generals are for instance believed to like dangerous games. The associations of particular deities can change over time; Hogu Pyŏlsŏng was for instance a goddess of smallpox, but after that disease's eradication in the 20th century retained associations with measles and chickenpox.
Popular cosmological deities include Ch'ilsŏng, the spirit of the seven stars of the Big Dipper, who is regarded as a merciful Buddhist figure that cares for children. Yŏngdŏng is a goddess of the wind, popular in southern areas including Jeju. The mountain god, or mountain gods more broadly, are called sansin, or sometimes sansillyŏng, and are typically seen as the most important spirits of the earth. Sansin is typically depicted as a man with a white beard, blue gown, and accompanying tiger. Water deities, or yong, are dragons deemed to live in rivers, springs, and the sea. The most senior dragon is the Yong-Wang (Dragon King) who rules the oceans. Spirits of military generals are sinjang, and include the obang changgun, the generals of the five cardinal points. Among the sinjang are historical figures like Ch'oeyŏng, Im Kyŏngŏp, Oh, and Chang, as well as more recent military figures; around Inchon, various mudang have venerated General Douglas MacArthur as a hero of the Korean War. Child deities are tongja. The Korean traditional cosmology also includes mischievous spirits called dokkaebi, and entities called tongt'o that can lodge in the family compound and cause trouble.

#### Village and household spirits

Villages traditionally had Jangseung, timber or occasionally stone posts representing two generals that guard the settlement from harmful spirits. On Jeju, these were constructed of volcanic rock and were respectively called the Harubang (grandfather) and Halmang (grandmother). Historically, villages would often hold annual festivals to thank their tutelary deities. These would often be overseen by local men and reflect Confucian traditions, although sometimes mudang did participate. In Korean society, rapid urbanisation has radically changed how people interact with their local deities.
Korean vernacular religion includes household deities, the chief of which is Sŏngju, the principal house guardian. Others include T'oju taegum, who patrols the precincts of the household, Chowang the kitchen spirit, and Pyŏnso Kakssi, the protector of the toilet. Keeping these entities happy was traditionally regarded as the role of the housewife, and is achieved through offering them food and drink. These informal rituals do not require the involvement of mudang, who would only be called in for special occasions. Pollution caused by births or deaths in the household are believed to result in Sŏngju leaving, meaning that he must be encouraged to return through ritual. Sŏngju may also require propitiation if expensive goods are brought into the home, as he expects a portion of the expenditure to be devoted to him.
Ancestral spirits are called chosang. Tutelary ancestors are termed tangju. Ancestors who may be venerated in musok rituals are broader than the purely patrilineal figures venerated in formal Korean ancestor veneration rites, the Jesa. These broader ancestors may for instance include those from a woman's natal family, women who have married out of the family, or family members who have died without offspring. While both the musok rites and the Confucian-derived jesa entail communication with ancestors, only the former involves direct communication with these spirits, allowing the ancestors to convey messages directly to the living. Certain ancestral spirits can also form part of a mudang's personal pantheon. A personal spiritual guardian is the momju (plural momjusin). The momjusin of male mudang are usually deemed female; those of female mudang are typically male.

### Cosmology and mythology

In Korean religion, a "fundamental cosmology" has influenced various traditions, including musok. Korean shamanic narratives include a number of myths that discuss the origins of shamans or the shamanic religion. These include, the Princess Bari myth, the Gongsim myth, and the Chogong bon-puri myth. Origin myths are often called ponp'uri. These narratives have been extensively collected and studied by Korean scholars. During a gut ritual held for the dead, an epic ballad called the Tale of Princess Pari is often recited.
One of the most widespread myths in Korean Shamanism is known as the Myth of Dangun, the legendary founder of the first Korean kingdom Gojoseon. Dangun is sometimes considered the first mudang. This myth refers to the belief that God would come from heaven. This would result in the earth and heaven being unified. God and human beings would be unified as well. Korean Shamanism believes that the goddess mother of earth is married to the heavenly God.
The Myth of Dangun has become the founding myth of the Korean nation.

### Birth and the dead

A common belief in Korean vernacular religion is that spirits of the dead wander the human world before entering the afterlife. After death, the soul must stand trial in court and pass through gates kept by the Ten Kings. At this court, the dead are judged for their conduct in life. The Ten Gates of Hell are regarded as places of punishment for the wicked, typified by grotesque and gory scenes. According to the Princess Bari narrative, Ascension from Hell to Paradise is possible through prayer and devotion.
The dead are regarded as intrinsically dangerous to the living as their touch causes affliction, regardless of whether they mean harm or not. Those who died prematurely or who feel their life was unfulfilled, such as grandparents who never saw their grandchildren, a first wife who was replaced by a second wife, those who died by drowning, and young people who died before they could marry, are all considered especially antagonistic to the living and thus particularly dangerous. Meddlesome ghosts are thought to often enter the house on a piece of cloth, clothing, or bright object. A dead ancestor who has not been appropriately cared or has been given an unsuitable burial place is deemed likely to cause trouble for its living descendants.
If a person suffers a tragic or untimely death, it is believed that their soul hovers between life and death and can cause misfortune for their family; they thus need to be dealt with through ritual. Terms for wandering spirits include jabkwi and kaeksa, and mudang are deemed best suited for dealing with them, because they can determine what they want and tell them to go away.
On Jeju Island, since the late 1980s there have been public lamentations of the dead involving simbang to mark those killed in the Jeju uprising of 1948.

## Practices
### Mudang

The mudang mediate between the human and supernatural worlds, doing so in an attempt to decrease human suffering and ensure a more harmonious life. Specifically, they interact with gods and ancestral spirits by divining their presence and will, performing small rituals to placate them and gain their favor, and overseeing the gut rituals to feast and entertain them. The mudang's ability to perform their rituals successfully is deemed to come from myŏnggi ("divine energy") bestowed upon them by the deities. Thus, divine favor must be gained through purification and supplication, prayer and pilgrimage. Individual mudang can be regarded as having particular specialities.
For the mudang, ritual is an economic activity, and they operate as free agents rather than members of an ordained clergy. For many practitioners, being a mudang is a full-time job on which they financially depend, although some fail to earn a living through this ritual vocation. To succeed financially, mudang must attract regular clientele, and to that end modern South Korean practitioners have advertised their services in brochures, fliers, newspapers, and on the Internet. Some followers of musok are unhappy with this situation, believing that the practice has degenerated under capitalism and modernisation; they feel that modern mudang display a more materialistic and self-interested approach than their historical predecessors.

#### Becoming a mudang

Many mudang report that they never wanted to take up the profession, resisting the calling due to the social disapproval that practitioners often face. However, musok teaches that it is the deities who decide if a person is to become a mudang and that they will torment an individual with misfortune, illness or madness to encourage them into adopting the profession. This process is termed the sinŭi kamul ("the drought caused by the gods"), sinbyŏng ("spirit possession sickness"), or mubyŏng ("mu sickness"). Mudang have for instance reported partial paralysis and hallucinations before turning to this ritual vocation, or else a compulsion to go to a shrine or sacred mountain. Alternatively, they have described encounters with spirits, sometimes while wandering in a wild environment, or otherwise through dreams, with dreams and visions sometimes revealing which deities the future mudang is expected to serve.
Once the person has accepted the calling, they must find an established mudang willing to train them. They become this person's apprentice, the chagŭn mudang. Apprentices are usually aged over 18, although there are examples of children becoming apprentices. The apprentice of a mudang may be called their sinttal or sinddal (spirit daughter) if female, or sinadul (spirit son) if male. The mudang will be that novice's sineomeoni. The neophyte must ultimately perform an initiation ritual to open up malmun (the "gates of speech") that will allow them to receive the words of the spirits. This rite is called the naerim gut. It involves the neophyte performing the appropriate chants, dances, and oracles to invoke and convey inspiration from the deities. If the initiate fails to perform this correctly, with the deities failing to open their malmun, they will have to perform it again. Many mudang perform multiple naerim gut before being recognised as properly initiated ritual specialists. Those mudang who fail to learn how to deal with supernatural entities correctly are sometimes called ōngt'ōri by other practitioners.
In the sesŭp-mu tradition, teachings are often passed down hereditarily although in other instances a sesŭp-mu adopts a non-relative, rather than their child, as an apprentice. Not all practitioners want their children to follow them into the profession, however. When mudang do not wish a family member to continue their vocation, they may ensure that their ritual paraphernalia is burned or buried at their death; doing so severs any connection between their person deities and their surviving family.

#### Clients of the mudang

Serving private clients is the core practice for most mudang, even those who have built celebrity status through their performance of staged gut. In some areas, including Jeju, clients are called tan'gol. Clients seek solutions to their practical problems, typically hoping that the mudang can ascertain the cause of misfortune they have suffered. Common reasons for doing so include recurring nightmares, concerns about a child getting into university, financial woes, business concerns, or physical ailments. Some clients turn to the mudang after being dissatisfied with the diagnosis or treatment administered by medical professionals.
Although both sexes do consult mudang, most clients are female. From his fieldwork in the 1990s, Chongho Kim found that most clients were women in their late fifties and early sixties, while that same decade Kendall noted that most clients in Seoul and its environs were small entrepreneurs, such as owners of small companies, shops, and restaurants. By the early 21st century, Sarfati observed, many young people had become clients of mudang as part of a spiritual search or for counselling. Clients do not generally regard themselves as being committed exclusively to musok, and may deem themselves Buddhists or Christians, but mudang often think that their rituals will please the spirits regardless of their client's beliefs.
A client will often arrive, greet the mudang, and then engage in an introductory conversation. Through this, the mudang will hope to ascertain more about the client and their problems. The mudang then uses divination and trance visions to determine the source of their client's trouble; in musok, neglecting ancestors and gods is seen as the primary cause of affliction. The mudang may then try to convince their client of the need for a particular ritual to treat their problem.
If a ritual fails to produce the desired result, the client may speculate that it was because of a bad performer, errors in the ritual, the presence of a ritually polluted attendee, or a lack of sincerity on their part. If the client feels the mudang has not successfully solved their problem, they may turn to another mudang. They may be disappointed or angry given their substantial financial investment; in some rare cases clients have sued mudang. The payment of money is often a source of mistrust between clients and mudang. Concerns about money are heightened by the lack of an "institutional buffer" between the client and ritual practitioner, such as a temple or church.

### Altars and shrines

Most musok rituals center around altars—referred to as sinbang, harabŏjiŭibang, or pŏptang—and which serve as places for mudang to engage with supernatural beings. Mudang typically have a shrine in their home in which they host various gods and ancestors, sometimes set up in a cabinet. Shrines might alternatively be found outdoors, often incorporating a stone or old tree, while a mudang will often establish a temporary altar in a client's home.
While each altar often has its own idiosyncratic elements, they are typically dominated by bright, primary colors, in contrast to the muted earth tones traditionally predominant in Korean daily life. This home shrine may include paintings of deities, called musindo, taenghwa, musokhwa, or sinhwa. These paintings are particularly important in the musok traditions of Seoul and of the northwest provinces Hwanghae and P'yŏngan; they were traditionally not found in parts of the south. Hanging above the altar, they are usually considered the most important objects present. They are regarded as seats for the deities, literally manifesting the latter's presence rather than just visually depicting them, an idea similar to those found across much of Asia, as in Buddhism and Hinduism. As well as being invited to inhabit a painting, a deity may also be petitioned to depart it; they are sometimes believed to leave of their own accord, for instance if they abandon a mudang who keeps the image.
Musindo paintings range from being crude to more sophisticated. Traditionally they use colors associated with the five directions (오방색; obangsaek): red, blue/green, yellow, white, and black. Painters who produce musindo are traditionally expected to adhere to standards of purity while producing these artworks, bathing beforehand and refraining from eating fish or meat. Since the 1970s, musindo have commonly been produced in commercial workshops, although a small number of traditional artists remain in South Korea. After a mudang's death, their musindo were often ritually de-animated and then burned during the 20th century. Some musindo have been donated to museums; certain musok practitioners believe that the deity leaves the image if that occurs.
On the shrine, deities may also be represented by sinsang, statues made of wood, plastic, clay, straw, or metal. Alternatively, deities may be represented by a white piece of paper, the kŭlbal or kŭlmun, onto which the entity's name is written in black or red ink. The deity may instead be seated in physical objects, including stones, clothing, coins, dolls, or knives; these may be concealed from view, for instance being wrapped in cloth or inside a chest. In addition to entities associated with musok specifically, shrines may also include images of Buddhist deities. Alongside representations of such beings, shrines typically have candles, incense holders, and offering bowls; there may also be toys or dolls to amuse the child gods. The mudang's altar will also often be a place to store or display their ritual paraphernalia, such as costumes.
To sustain their ongoing favor, mudang often worship their deities daily. Thus, they often bow when in the presence of their home shrine, and then place offerings upon it. Some offerings, such as cooked rice, fruit, and water, may be changed daily; others, such as sweets, cigarettes, and liquor, may be replaced more infrequently. Mudang maintain that they provide offerings in thanks for the work their deities have brought them. For visiting clients, who may also place offerings at a mudang's home-shrine, a large assortment of offerings thus gives the impression of a financially successful ritual specialist.
Deities are often believed to be present in all houses. Historical accounts often reference the presence of earthen jars (tok, hangari, tanji) filled with grain, or smaller baskets or pouches, as offerings to household deities and ancestors. This practice was declining in South Korea by the 1960s and 1970s. By the latter decades of the 20th century, cardboard boxes had become common receptacles for these household offerings. Some mudang have suggested that, because most South Koreans now live in apartments, the Sŏngju must be venerated in a way that ensures it is mobile and can be transported to a new home.

#### Guttang and pugundang

Specialised buildings at which musok rituals are performed are called guttang or gut dang (굿당) and are typically located on mountains. Guttang are often identified on the exterior by a t'aegŭk symbol, a circular swirl of red, blue, and yellow that symbolizes the cosmos. The main ritual room is called the gut bang, and often contains a table on which offerings are placed. Mudang often rent a guttang to perform their rituals, especially if they do not have space for such rites in their home.
Practitioners often believe that deities communicate with humans through dreams as a means of choosing specific locales for the placement of guttang. Some are located at especially auspicious places, such as at an area below a mountain, the myŏngdang, where positive spiritual energy is thought to congregate. Guttang sometimes move over time. The Guksadang, which Kendall described as "Seoul's most venerable guttang", for instance was originally on South Mountain, before being displaced by a Shinto shrine during the Japanese occupation, at which it moved to Inwangsan, a mountain to the north of the city. The growing urbanisation of South Korea since the late 20th century has meant that many are now surrounded by other buildings, sometimes including other guttang. The increasingly cramped nature of Korean urban living may have encouraged the increasing popularity of guttang in isolated locations like mountains.
Guttang often operate as businesses. They rent out rooms for mudang to use, a practice perhaps originating in the late Joseon period. The guttang will have a shrine keeper, who may be a mudang themselves. Other staff based there may include musicians called chaebi, cooks who prepare food for gut rituals, and a maid, the kongyangju, who is a trainee mudang yet to undergo their initiation rite. As well as spaces for ritual, guttang also provide places for networking, allowing mudang to witness the rituals of other practitioners and observe different regional styles.
Shrines dedicated to significant tutelary spirits are known as tang or pugundang. Historically, these were often the foci for local cults, such as those devoted to apotheosised heroes. In parts of South Korea, as on Jeju Island, new village shrines have continued to be created into the early 21st century, with various Jeju villages having more than one shrine.

### Gut rites

The central ritual of the mudang is called gut. These are large-scale rites, characterised by rhythmic movements, songs, oracles and prayers. They are the only rituals in traditional Korean religion believed to give supernatural entities the ability to speak directly to humans, and are meant to create welfare, promoting commitment between supernatural beings and humankind. The purpose of a gut is to get the supernatural beings to communicate, expressing what it is that they want and why they are angry. There is regional diversity in the styles of gut, although some mudang mix these different styles, with each gut displaying features unique to its particular circumstances. Central to musok rituals is a reciprocal transaction between humans and supernatural entities. These rituals are typically performance-focused, rather than being rooted in a prescribed liturgy, and can last for up to several days.
A gut is sponsored for a specific purpose. A gut may be arranged due to an illness, domestic quarrel, or financial loss. It might be undertaken to propitiate the spirit of a deceased family member, or to increase prosperity and good fortune; in the 21st century, it has become increasingly common to sponsor a gut to mark a new financial venture, such as the opening of a mall or an office building. As well as being performed for clients, the mudang will sometimes perform these rituals for their own personal reasons; in the 1990s, for instance, the prominent mudang Kim Kŭm-hwa performed a gut for Korean reunification.
Financial payment for a gut is typical, although the fee varies between mudang and the circumstances of the rite. However, a gut is usually very expensive for the client of a mudang; based on his fieldwork in the 1990s, Chongho Kim noted that a gut in Seoul typically cost between 2 and 5 million won, whereas in the rural area of Soy it cost between 300,000 and 2.5 million won. The precise fee may be negotiated between the mu and their client, sometimes involving haggling. This will usually be agreed at a pre-gut consultation. As well as paying for the mudang's time, the fee also covers the wages of any assistants and the costs of material used in the rite; it may also reflect the years of training they have undertaken to be able to perform these rituals.
The gut is usually held in private, and few have a larger audience than the direct participants like the client, although there are instances where those paying for a gut will invite neighbors to observe. On occasion, a busy client will not attend the gut they have sponsored. These rituals are typically regarded as unsuitable for children to attend. Often it will take place outdoors and at night, in an isolated rural location, at a guttang shrine rented for the occasion, or in a private home, either that of the mudang, or that of their client. Setting up the gut may involve not only the mudang but also their apprentices, assistants, musicians, butchers, and cooks. Preparing and decorating the space is deemed a meaningful part of the ritual process, with those setting it up often concerned so as not to offend the spirits.
Colorful paintings of the gods will often be brought into the space where the gut is to be performed; this is not part of the gut performed by Jeju simbang. God paintings are usually paper, although in modern contexts are sometimes polyester, ensuring that they are resistant to rain and tearing. Other practitioners regard the use of polyester images as a corruption of tradition. These images are then often hung on a metal frame. In Taejŏn City and Ch'ungch'ŏng province, a traditional practice involves decorating the ritual space with handmade mulberry paper cut into patterns. Various ritual items may be included in the gut ritual, including swords, the samjichang, a drum, drum stick, and the spirit stick. The samjichang is a three-pronged spear. The chukwonmun is a prayer card used in the gut onto which information like the name of the client may be written. The chukwonmun may then be attached to a drum.

#### Offerings at the gut

At gut, food is offered to the spirits. This will often include fish, rice, tteok rice cakes, eggs, sweets, nuts, biscuits, fruit, and meat. Some of this food will be cooked, some will be offered raw. To provide meat, animal sacrifice occurs at most gut, although is rare in televisual, cinematic, and museum depictions of these rites. A cow or pig killed for the purpose may be butchered in the shrine room; the carcass may be impaled on the trident; if it fails to balance, then this is seen as evidence that the deities do not accept the offering. When the ritual is intended to invoke Buddhist spirits, the food offerings may be vegetarian; offering these entities meat would offend them. Food offerings may also be set out at the side for wandering spirits who are attracted by the ritual, an act designed to avoid mishaps they could cause.
Offered alongside the food will often be alcoholic drinks, typically soju, as well as non-food items like incense, cloth, money (both real and imitation), and paper flowers. The color of the flowers may indicate to whom they are offered; pink for the spirits of military generals, white for Buddhist deities, and multi-colored for ancestral spirits. The material used for the gut will often be bought in a manmulsang shop, which specialises in traditional religious paraphernalia. In modern South Korea, the ritual paraphernalia used is often of poor quality because it is intended to be burnt following the ceremony.
These may be placed on offering tables; one table will be the halabeoji sang, devoted to the musok gods, while the other table will be the jasang sang, devoted to ancestral spirits. The mudang will often perform divination to determine if the offerings have been accepted by the supernatural beings. It is considered important for the person giving these offerings to do so with sincerity and devotion, with the mudang undertaking a form of divination called "weighing the sincerity" (chŏngsŏng kŭllyang) to determine if this has been the case. The emotional influence on the audience is considered evidence of its efficacy.
During the ritual, attendees may be expected to give additional offerings of money to the mudang, often while they are possessed, intended as thanks both to them and to the spirits. These offerings, given in addition to the ritual fee, are called pyŏlbi or kajŏn. Any real money presented as offerings to the deities will be taken by the mudang. Much of the food assembled for the gut will then be distributed and consumed by the attendees at the end of the ritual, having been charged by auspiciousness by its involvement in the rite. Attendees may distribute some of this food to non-attendees once they get home; they may also set some aside to feed any wandering spirits that might have followed them from the gut. In some gut, especially those held at gut dang shrines, food will also be left to decay.

#### Performance at the gut

The ritual begins with the mudang inviting supernatural entities to the altar, after which they set out to entertain them. Music will often be involved in the gut. Musical instruments typically involved in gut include cymbals, hourglass-shaped drums called changgu, and a gong. Also sometimes featured is a pipe, the piri. The gut will often begin with drumming. The mudang will often dance to the beat of the drums, often swirling in circles, something believed to facilitate the possession trance. They may hold nŏk-chong, short sticks to which white paper streamers are attached; this helps channel the spirits into the mudang's body. The mudang may also carry a fan and brass bells; Sarfati commented that these bells were "a central symbol of musok", and their purpose is to attract the attention of the spirits.
The language used by a mudang during their rite is called mudang sori ("mudang's sounds"), and is often deliberately archaic. The songs or chants employed are called muga, with each practitioner having their own personal repertoire, largely inherited through oral tradition. As well as traditional folk songs, some mudang have sung pop songs to entertain the spirits. Incantations and ritual words for communicating with the spirit are called chukeon. The mudang will often recite mythological stories during the ritual, something deemed to contribute to its efficacy. These may be recited in full at a longer ritual or in condensed form for a shorter one. There may be breaks during the gut, for instance giving time for the participants to eat.
The costumes worn for these rituals are called sinbok. These colorful outfits resemble those documented from the 19th and early 20th centuries, and may involve a hanbok. The mansin may distinguish themselves from their assistants by having their hair in the Tchokchin mŏri style. For the gut, the mudang will dress in clothes representing the deities, with different deities associated with different items of clothing. They may change outfit over the course of the gut to reflect the different entities possessing them. This is not a practice that the sesup mu engage in.
Also used in many gut are chaktu blades, objects symbolizing the bravery of the possessing warrior spirits. The mudang may stab themselves in the chest with the knives, run the blade along their tongue, or press it to their face and hands. Riding knives is termed jakdugeori and involves the mudang walking barefoot on the upturned blade of the knife, sometimes while speaking in gongsu, or possessed speech. Practitioners claim that it is the spirits that prevent the mudang from being cut by the blade, and the ability to undertake such dangerous acts without harm is regarded as evidence for the efficacy of the rite. Some practitioners acknowledge instances in which they have been cut by the blades. Jakdugeori has become an expected part of staged or cinematic gut.
The possession phase takes place at the climax of the ritual. In some gut traditions, the mudang will stand upon an earthen jar while doing so. The term sin-naerim (descending of the spirits) describes possession of the mansin, intended in a manner that is largely controlled. Possessed speech is called kongsu; words from the possessing entity will then be spoken to the assembled persons by the mudang. Over the course of a gut, a mansin may be possessed by a succession of different supernatural entities. On Jeju, the simbang will provide a voice for the spirits. Yun noted that the simbang's "so-called medium speech" typically lacked the "dramatic intensity" of the messages conveyed by the kangsin-mu. The entities possessing the mudang will typically dispense advice to the ritual's sponsor and to other attendees. Supernatural beings will often relate that if a gut had been performed earlier, misfortune would not have befallen the person sponsoring the gut.
The final phase of the gut entails sending off the spirits who have been summoned, often by burning name tags, the josang ot ("clothes for ancestors") or cloth, straw shoes, and imitation money. Towards the end of the gut, wandering spirits that may have gathered are expelled, talismans may be distributed to attendees, and finally the mudang will remove their ceremonial clothing.
Male mudang often wear female clothing and makeup when performing rituals, reflecting their possession of a female monjusin. Female mudang may show an interest in smoking, drinking alcohol, and playing with bladed weapons, reflecting that they have a male monjusin. In Korean society, there have been persistent rumours about the toleration of homosexuality within musok practitioners.
Mudang sometimes work in groups. This has been observed among simbang on Jeju, as well as mansin in Seoul. In the early 1990s, for example, a feminist group in Seoul sponsored several mudang to perform a gut ritual for the aggrieved souls of Korean "comfort women". When an arsonist torched Seoul's historic Namdaemun Gate in 2008, several mansin performed a ritual to appease spirits angered by the act.

#### Styles of gut

Different types of gut have different names, often reflecting the principle deity being honoured or the purpose of the rite. The chesu gut is for good fortune, while the uhwan gut is for healing. The chinogi gut is performed to send ancestors to a good afterlife. The mich'in gut is performed for a person who is mentally afflicted and often deemed to be possessed by one or more spirits. Exorcisms will often involve throwing scraps of food, sometimes at the afflicted person. The possessing spirit is offered food to encourage it to leave. The ch'a kosa is performed to honor the spirits of a new car and became increasingly popular as car ownership grew in late 20th century South Korea.
The kkonmaji gut or flower-greeting gut is an annual rite held by a mudang to entertain and feed their gods, ancestors, and clients. The sin gut are performed in gratitude to the deities and ancestors for granting a mu their spiritual power and thus a livelihood. They are regarded as returning to these supernatural beings a portion of what the mu has earned. The sin gut can sometimes last 10 days. The byong gut is a ritual for expelling bad spirits, sometimes from a human. This sometimes involves the spirit forcing it into a bottle.
Historically, the gut may have had entertainment value when there were few other outlets. Since the latter decades of the 20th century, gut performed primarily for entertainment purposes rather than for religious reasons are referred to as gut gongyeon. Some practitioners who perform both draw a clear distinction between them, although many mudang still regard staged gut as genuine interactions with spirits. Performed in museums or at city festivals, these gut often take place on raised stages surrounded by a seated audience, typically attracting journalists, scholars, and photographers. Staged gut are often dedicated to general causes such as national prosperity; sometimes the food placed as an offering is fake. They often involve folklorists or other scholars who explain the ritual to the audience, while the participants will often be dressed in a common uniform, something not found in private gut. Mudang may see these staged rituals as an opportunity to attract potential new clients, uploading videos of them performing such rites to social media and YouTube.
Gut gongyeon are often performed for their artistic value. By 2009, South Korea's government recognised ten regional gut styles as parts of the country's intangible cultural heritage, and that year one of these traditions – the Yŏngdŭng gut performed at Ch'ilmŏri Shrine on Jeju – was added to UNESCO's Representative List of the Intangible Cultural Heritage of Humanity.

### Purification

Purity of both the body and the mind is a state that is required for taking part in rituals. Purification is considered necessary for an efficacious communion between living people and ancestral forms. Before any gut is performed, the altar is always purified by fire and water, as part of the first gori of the ritual itself. The colour white, extensively used in rituals, is regarded as a symbol of purity. The purification of the body is performed by burning white paper.

### Mountains, landscape, and pilgrimage

In musok, spiritually potent sites include rocks, springs, and sŏn'ang trees. The latter trees may be marked out by having strips of cloth or paper attached to them. Mountains are often deemed places of sacred presence and associated with musok's origin. Each prominent mountain is deemed to have a sovereign mountain spirit. The levels of spiritual power at a mountain are influenced not just by its associated deities but also the ki energy (the equivalent of the Chinese qi) that is present there. This ki is believed to channel through maek ("veins") through the mountain landscape; these can be disrupted by roads or other construction. Thus, the potency of these mountains is thought to decline amid growing urbanisation and tourist access. In Korea, this traditional geomancy is called p'ungsu, and is akin to the Chinese fengshui.
Pilgrimages to mountain shrines have long been part of Korean religion. Historically, the mudang's mountain pilgrimages were rare events, although improved transportation meant that by the 1990s these had become more regular occurrences in South Korea. Some mudang prepare for these pilgrimages by bathing and abstaining from eating meat, fish, or eggs. On arrival at the shrine, the pilgrim will bow and give offerings. For mudang, these mountains are places to replenish their myŏnggi and are conducive to receiving visions. Mudang will make offerings not only at the mountains but also at springs and guardian trees en route. Those reaching the summit of a mountain will often add a pebble to a cairn to propitiate that mountain's sansin. Incorrectly performing the pilgrimage may upset the sansin and bring about this spirit's retribution.
The most sacred mountain for the mudang is Mount Paektu, located on North Korea's northern border with China; this is believed to channel ki to every other mountain in the peninsula. According to legend, it is also the birthplace of Tan'gun, the national ancestor and first mudang. Since the 1990s, mudang from South Korea have travelled to China to make pilgrimages to this mountain.

### Talismans and divination

An important component of the mudang's role is to produce talismans called pujŏk (bujeok) which are presented as providing the bearer with good fortune. These pujŏk are often based on Hanja, Korean versions of Chinese logograms. These may be distributed to attendees at the end of a rite. Clients will often affix these to the internal walls of their home.
Divination is termed jeom. One form of divination, sometimes performed during other rituals, involves a person picking one of a selection of rolled up silk flags; the color of the selected flag is then interpreted as bearing meaning for that individual. Green and yellow flags are often seen as indicating bad fortune, while red is regarded as being auspicious. The mugŏri style of divination involves casting rice and coins onto a tray, while another practice entails shaking rice kernels onto a person's lap and then drawing meaning from whether they are of an odd or even number.
In Korean vernacular religion, there are also ritual specialists who perform divinations and produce amulets but who do not engage in gut rituals like the mudang.

## History

It is difficult to determine the origins of musok. Detailed accounts of mudang rituals prior to the modern period are rare, and the fact that the tradition is orally transmitted means it is difficult to trace historical processes.

### Prehistory

Some historians have argued that musok has common origins with other traditions labelled "shamanic" in parts of North Asia, suggesting a common origin in prehistory. Korean shamanism goes back to prehistoric times, pre-dating the introduction of Buddhism and Confucianism, and the influence of Taoism, in Korea. Over time, elements from other traditions, such as Buddhism, Confucianism, and Daoism, were absorbed into its practices. Vestiges of temples dedicated to gods and spirits have been found on tops and slopes of many mountains in the peninsula.
Shamanism can be traced back to 1,000 BC. The religion has been part of the culture of the Korean Peninsula since then. "Historically, Korean Shamanism (Musok) was an orally transmitted tradition that was mastered mainly by illiterate low-ranking women within the neo-Confucian hierarchy." However, several records and texts have documented the origin of Korean Shamanism. One of these texts is Wei Shi which traces Shamanism to the third century. Chinese dynastic histories mention the importance of designated shamans among early religious practices in Japan but not Korea. The Korean studies scholar Richard D. McBride thus asserts that non-shamans were able to practice "under their own authority". Evidently, the history of Korean Shamanism remains a mystery. However, foreign religions, including Christianity, Buddhism, Confucianism and Taoism have influenced the development of Korean Shamanism.
The development of Korean Shamanism can be categorized into different groups. The first category involves simple transformation. In this transformation, the influence of the practices and beliefs of other religions on Korean Shamanism was superficial. The second category of transmission was syncretistic. This category involves Shamanism being incorporated into the practices and beliefs of other cultures, including Confucianism, Christianity, Taoism, and Buddhism. These religions had different levels of influence on Korean Shamanism. The third category involves the formation of new religions through the mixing of beliefs and practices of Shamanism with those of other dominant religions.
Although many Koreans converted to Buddhism when it was introduced to the peninsula in the 4th century, and adopted as the state religion in Silla and Goryeo, it remained a minor religion compared to Korean shamanism.
The term mu is first recorded in the 12th-century Yisanggugjip. It also appears in the Samguk sagi from that century. The use of images of the musok deities, hanging on the wall, is first recorded from the 13th century.

### Joseon Korea and Japanese occupation

The Goryeo kingdom was replaced by the Joseon dynasty, which saw an increase in governmental persecution of the mudang. Confucianism was the dominant ideology in Joseon Korea, contributing to these suppressions; later historians argued that this was connected to the elite's desire to gain more power by challenging rivals to their Confucian system. Confucians accepted the existence of the spirits invoked in the mudang's rites, but argued that there were better ways of dealing with these supernatural beings. They regarded the musok rituals as improper, criticising the presence of both sexes together in environments where alcohol was being consumed. Korea's Neo-Confucian scholars used the derogatory term ŭmsa for non-Confucian ceremonies, of which they considered the mudang rituals among the lowest.
In the Joseon dynasty, mudang belonged to one of eight outcast groups that were expelled from the capital city. The Gyeonggukdaejeon law book prescribed 100 lashes in public for anyone found to be supporting them. This persecution could prove deadly; in an extreme case, a mudang was beheaded in 1398. In an oft-cited incident, Jeju governor Yi Hyŏngsang initiated a purge of simbang on the island in 1702, destroying 129 shrines. Taxes were levied on the mudang's rituals, both to discourage the practice but also to raise revenues for the government; these taxes remained in place until the 1895 Kabo reforms. At the same time as the government persecuted the mudang, they also turned to them in emergencies like epidemics, droughts, and famines. Several mudang were permitted access to the royal palaces, where several structures were set aside for their usage.
By the late 19th century, many Korean intellectuals eager for modernisation came to regard musok as superstition that should be eradicated; they increasingly referred to it with the term misin ("superstition"). These ideas were endorsed in Tongnip sinmun, Korea's first vernacular newspaper. Many of these intellectuals were Christian, thus regarding the mudang's spirits as evil demons. In 1896, police launched a crackdown by arresting mudang, destroying shrines, and burning paraphernalia.
The Japanese Empire invaded Korea in 1910. During the Japanese occupation, the occupiers tried to incorporate musok within, or replace it with, State Shinto. The Japanese colonial Governor-General of Chōsen presented the mudang as evidence for Korean cultural backwardness, an approach intended to legitimize Japanese imperial rule. Japanese efforts to suppress the tradition included the Mind Cultivation Movement launched in 1936. Korean elites largely supported these suppressions for a variety of reasons, one of which was to demonstrate Korean cultural advancement to the Japanese occupying Korea.
It was in this colonial context that scholars developed the idea that the mudang were continuing an ancient Korean religion and thus represented the spiritual and cultural repository of the Korean people. Influenced by the Western use of the term "shamanism" as a cross-cultural category, some Korean scholars speculated that the mudang tradition descended from Siberian traditions. The Japanese scholar Torii Ryūzō proposed the mudang as a remnant of a primordial Shinto, with both stemming from Siberian "shamanism". These ideas were built on by nationalist Korean scholars Ch'oe Nam-sŏn and Yi Nŭnghwa in the 1920s. Cho'e reversed Torii's framework by emphasising the primacy of ancient Korean over Japanese tradition as the transmitter of Siberian religion, while Yi promoted the mudang tradition as the residue of what he called sin'gyo ("divine teachings"), meaning a primordial Korean religion that lost its purity through the arrival of Confucianism and Buddhism. At the time, Korean elites remained wary about this new positive reassessment.

### Korean War and Division

The situation for Musok worsened after the division of Korea and the establishment of a northern Socialist government and a southern pro-Christian government. The Korean War and subsequent urbanisation of Korean society resulted in many Koreans moving around the peninsula, impacting the distinct regional traditions of the mudang. Many mudang from Hwanghae (in North Korea) resettled in Inchon (in South Korea), strongly influencing musok there, for example. This migration meant that by the early 21st century, kangsin-mu were increasingly dominant in areas like Jeju where sesŭp-mu historically predominated, generating rivalry between the two traditions.
In North Korea, most formal religious activity was suppressed, with mudang labelled part of the "hostile class". In South Korea, Christianity spread rapidly from the 1960s, becoming the country's dominant religion by the 21st century. South Korean leader Syngman Rhee launched the Sin Saenghwal Undong ("New Life Movement") which destroyed many village shrines. This policy continued as the Saemaul Undong ("New Community Movement") of his successor, Park Chung Hee, which led to a surge in the police suppression of mudang during the 1970s. In response, mudang formed the Tae Han Sŭngkong yŏngsin yŏnhap-hoe (Korean Victory Over Communism Federation of Shamans) to promote their interests, its name reflecting the pervasive anti-communist atmosphere of South Korean society. Such outright persecution ended after Park's assassination in 1979.
The popularization of folklore studies in the 1970s resulted in the notion of musok as Korea's ancient tradition gaining acceptance among growing numbers of educated South Koreans. In 1962, South Korea had introduced a Cultural Properties Protection Law that recognised performing arts as intangible cultural heritage; some folklorists used this to help defend the mudang. In the latter part of the 20th century, the mudang rituals were increasingly revived as a form of theatrical performance linked to cultural conservation and tourism. From the 1980s onward, South Korea's government designated certain mudang as Human Cultural Treasures. One of the best-known examples was Kim Geum-hwa, who from the 1980s performed for foreign anthropologists, toured Western countries, and appeared in documentaries. Reflecting the view of musok as an important part of Korea's cultural heritage, a gut was depicted on a South Korean postage stamp while musok elements were included at the Seoul 1988 Olympic Arts Festival and the 1988 inauguration of President Roh Tae-woo. Paintings of musok deities became increasingly collectable in the 1980s and 1990s.
The mudang were often regarded favorably within South Korea's minjung (Popular Culture Movement) pro-democracy campaign from the 1970s; several mudang were active in the movement and became emblematic of its struggle. Advocacy groups were also formed to advance the cause of the mu, keen to present the tradition as lying at the heart of Korean culture, while the 1980s also saw mudang begin to write books about themselves. Mudang also adapted to new technologies; from the 1990s they increasingly used the Internet to advertise their services, while portrayals of mudang became widespread on South Korean television in the 2010s. This increasing cultural visibility improved the mudang's social image.
Since the early 19th century, a number of movements of revitalization or innovation of traditional Korean shamanism arose. They are characterized by an organized structure, a codified doctrine, and a body of scriptural texts. They may be grouped into three major families: the family of Daejongism or Dangunism, the Donghak-originated movements (including Cheondoism and Suunism), and the family of Jeungsanism (including Jeung San Do, Daesun Jinrihoe, the now-extinct Bocheonism, and many other sects).

## Demographics

Most mudang are female, something that may connect to origin myths that present musok as first developing among women. Approximately a fifth of mudang are male, although the latter are proportionately over-represented in 21st-century media representations. There is regional variation in these gender differences; on Jeju Island, there were more male than female simbang prior to the 1950s, and proportions of male practitioners remain higher there than on the Korean mainland. Mudang have conventionally belonged to the lowest social class; Chongho Kim noted that most mudang he encountered in the 1990s were both financially poor and had little formal education.
Determining the number of mudang is difficult. In 1983, around 43,000 people were members mudang unions, while in the early 21st century, Sarfati estimated the number of mudang at being over 200,000. Rather than being evenly distributed throughout South Korea, concentrations were higher in Seoul, and on Jeju. The number of mudang as a whole does not appear to be decreasing, although the hereditary sesŭp-mu, including the Jeju simbang, are "in steep decline". Musok is not recorded in the South Korean census because the government does not regard adherence to it as being akin to identifying as a Christian or a Buddhist. A late 20th-century survey by the Korean Gallup Research Institute indicated that 38 percent of the adult population of South Korea had used a mudang. In North Korea, according to demographic analyses by Religious Intelligence, approximately 16 percent of the population practises "traditional ethnic" religion.
Since at least the 20th century, mudang have travelled abroad to perform rituals; many for instance serve clients in Japan's Korean minority. There are also mudang in Europe, and a small number of non-Koreans have become mudang; a 2007 documentary covered the story of a German mudang. Kendall noted the existence of one mudang living outside Korea who was promoting their teachings through New Age-style workshops.

## Reception

Musok has been suppressed throughout Korean history under a succession of dominant ideologies including Confucianism, Japanese colonialism, and Christianity. At the start of the 21st century, the mudang remained widely stigmatized in South Korean society, facing widespread prejudice. In 2021, Sarfati observed that while the religion was "still stigmatized", it was experiencing "growing acceptance" in South Korea.
The religion's critics often regard mudang as swindlers, people who manipulate the gullible. Critics regularly focus their critique on the large sums of money that the mudang charge, and maintain that the expenses required for its rituals are wasteful. Critics have also accused mudang of disrupting the civil order with their rituals. Kendall noted that there was a "generally adversarial relationship" between mudang and Protestants in South Korea, the latter regarding musok as "Devil worship", although there are also Protestants who have commissioned gut. Mainline Protestant theologians have sometimes blamed musok for predisposing Koreans to Pentecostalism and the idea that prayer can generate financial reward. Christians have sometimes harassed mudang at their places of work or during their ceremonies, something which mudang regard as religious discrimination.
Mudang began appearing in South Korean film in the 1960s. Early portrayals in the 1960s and 1970s generally showed them as harmful, frightening, and anti-modern figures, as in Ssal (1963), Munyŏdo (1972) and Iŏdo (1977). From the mid-2000s, films increasingly portrayed them as members of a living tradition situated in modern urban environments, as in Ch'ŏngham Posal (2009) and Paksu Kŏndal (2013). The 2000s also saw several successful documentaries about mudang appear in Korean cinemas, as well as increasing appearances of mudang on Korean television. Korean artists who have cited musok rituals as an influence on their work include Nam June Paik, who recreated an exorcism gut for several performances from the late 1970s. Musok has also been presented in museums, although often with emphasis placed on its folkloric and aesthetic value rather than its role as a religious practice. South Korea's government often embrace gut as a traditional performing artform, but marginalise its religious function.
Musok has influenced some Korean new religions, such as Cheondoism and Jeungsanism, and some Christian churches in Korea make use of practices rooted in musok.
