Information: - A demon (from Koine Greek "daimonion") is a supernatural, often malevolent being prevalent in religion, occultism, literature, fiction, mythology and folklore. - The Exorcist is a 1971 novel by American writer William Peter Blatty . The book details the demonic possession of twelve - year - old Regan MacNeil , the daughter of a famous actress , and the Jesuit psychiatrist priest who attempts to exorcise the demon . Published by Harper & Row , the novel was the basis of a highly successful film adaption released two years later , whose screenplay was also written by Blatty . The novel was inspired by a 1949 case of demonic possession and exorcism that Blatty heard about while he was a student in the class of 1950 at Georgetown University . As a result , the novel takes place in Washington D.C. near the campus of Georgetown University . In September 2011 , the novel was reprinted by Harper Collins to celebrate its fortieth anniversary , with slight revisions made by Blatty as well as interior title artwork by Jeremy Caniglia . - Religion is a cultural system of behaviors and practices, world views, sacred texts, holy places, ethics, and societal organisation that relate humanity to what an anthropologist has called "an order of existence". Different religions may or may not contain various elements, ranging from the "divine", "sacred things", "faith", a "supernatural being or supernatural beings" or "some sort of ultimacy and transcendence that will provide norms and power for the rest of life." - Presbyter (Greek , : "elder" or "priest" in Christian usage) in the New Testament refers to a leader in local Christian congregations, with presbyter being from the Greek ""presbyteros"" and meaning elder/senior and episkopos meaning overseer, referring exclusively to the office of bishop, but with presbyteros being understood by many as referring to the same person functioning as overseer. In modern Catholic and Orthodox usage, presbyter is distinct from "bishop" and synonymous with "priest". However, in predominant Protestant usage, the term is not seen as referring to a member of a distinctive priesthood called "priests," but instead terms such as "minister", "pastor" and "elder" are used. - Demonic possession is the belief that individuals can be possessed by malevolent preternatural beings, commonly referred to as demons or devils. Obsessions and possessions of the devil are placed in the rank of apparitions of the evil spirit among men. It is obsession when the demon acts externally against the person whom it besets, and possession when he acts internally, agitates them, excites their ill humor, makes them utter blasphemy, speak tongues they have never learned, discovers to them unknown secrets, and inspires them with the knowledge of the obscurest things in philosophy or theology. Descriptions of demonic possessions often include erased memories or personalities, convulsions (i.e. epileptic seizures or fits) and fainting as if one were dying. Other descriptions include access to hidden knowledge (gnosis) and foreign languages (xenoglossy), drastic changes in vocal intonation and facial structure, the sudden appearance of injuries (scratches, bite marks) or lesions, and superhuman strength. Unlike in channeling, the subject has no control over the possessing entity and so it will persist until forced to leave the victim, usually through a form of exorcism. - William Peter Blatty (January 7, 1928 January 12, 2017) was an American writer and filmmaker best known for his 1971 novel "The Exorcist" and for the Academy Award-winning screenplay of its film adaptation. - Knowledge is a familiarity, awareness or understanding of someone or something, such as facts, information, descriptions, or skills, which is acquired through experience or education by perceiving, discovering, or learning. - Regan Teresa MacNeil (born November 11, 1961) is a fictional character from William Peter Blatty's horror novel and film, "The Exorcist" and its first sequel, "". In both films, she was portrayed by Linda Blair. - Sacrifice is the offering of food, objects or the lives of animals to a higher purpose, in particular divine beings, as an act of propitiation or worship. While "sacrifice" often implies ritual killing, the term offering (Latin "oblatio") can be used for bloodless sacrifices of food or artifacts. For offerings of liquids (beverages) by pouring, the term libation is used. - A ritual "is a sequence of activities involving gestures, words, and objects, performed in a sequestered place, and performed according to set sequence." Rituals may be prescribed by the traditions of a community, including a religious community. Rituals are characterized but not defined by formalism, traditionalism, invariance, rule-governance, sacral symbolism, and performance. - The Devil (from Greek: or "diabolos" slanderer or accuser) is, according to Christianity and Islam, the primary opponent of God. - Linda Denise Blair (born January 22, 1959) is an American actress. Blair is best known for her role as the possessed child, Regan, in the film "The Exorcist" (1973), for which she was nominated for an Academy Award and won a Golden Globe. She reprised her role in "" (1977), for which she was nominated for a Best Actress Saturn Award. - Xenoglossy, also written xenoglossia, sometimes also known as xenolalia, is the putative paranormal phenomenon in which a person is able to speak or write a language he or she could not have acquired by natural means. The words derive from Greek ("xenos"), "foreigner" and ("glssa"), "tongue" or "language". The term xenoglossy was ostensibly coined by French parapsychologist Charles Richet. Stories of xenoglossy are found in the Bible, and contemporary claims of xenoglossy have been made by parapsychologists and reincarnation researchers such as Ian Stevenson. There is no scientific evidence that xenoglossy is an actual phenomenon. - A priest or priestess (feminine) (from Greek "presbyteros" through Latin "presbyter", "elder", or from Old High German "priast", "prest", from Vulgar Latin "provost" "one put over others", from Latin "praepositus" "person placed in charge"), is a person authorized to perform the sacred rituals of a religion, especially as a mediatory agent between humans and one or more deities. They also have the authority or power to administer religious rites; in particular, rites of sacrifice to, and propitiation of, a deity or deities. Their office or position is the priesthood, a term which also may apply to such persons collectively. - An epileptic seizure, also known as an epileptic fit, is a brief episode of signs or symptoms due to abnormal excessive or synchronous neuronal activity in the brain. The outward effect can vary from uncontrolled jerking movement (tonic-clonic seizure) to as subtle as a momentary loss of awareness (absence seizure). Diseases of the brain characterized by an enduring predisposition to generate epileptic seizures are collectively called epilepsy. Seizures can also occur in people who do not have epilepsy for various reasons including brain trauma, drug use, elevated body temperature, low blood sugar and low levels of oxygen. Additionally, there are a number of conditions that look like epileptic seizures but are not. A first seizure generally does not require long term treatment with anti-seizure medications unless there is a specific problem on either electroencephalogram or brain imaging. 510% of people who live to 80years old have at least one epileptic seizure and the chance of experiencing a second seizure is between 40% and 50%. About 50% of patients with an unprovoked apparent "first seizure" have had other minor seizures, so their diagnosis is epilepsy. Epilepsy affects about 1% of the population currently and affected about 4% of the population at some point in time. Most of those affectednearly 80%live in developing countries.
