Sevā

Sevā (also transcribed as sewa, Sanskrit: सेवा) is the concept of selfless service that is performed without any expectation of reward for performing it. It is predominant in Hinduism and Sikhism. Such services can be performed to benefit other human beings or society. Sevā means "selfless service". A more recent interpretation of the word is "dedication to others". Langar and Bhandara are some of the most celebrated seva in Sikhism and Hinduism.
In Hinduism, it is also known as karma yoga, as described in the Bhagavata Gita. In Sikhism seva is an act of service to Waheguru (Supreme God), and it is a way to become closer to Waheguru. The principles of seva underpin many Sikh values. The Guru emphasizes this concept numerous times in the Guru Granth Sahib. The text focuses on the state of mind when practicing seva, the spiritual benefits of doing seva, and how one should perform it.
Seva comes from the Sanskrit root sev-, "to serve", and is a central concept in both contemporary Hinduism and Sikhism.
In Hinduism, seva means selfless service and is often associated with karma yoga (disciplined action) and bhakti yoga (disciplined devotion). Seva is also connected to other Sanskrit concepts such as dāna (gift giving), karunā (compassion), and preman (kindness). Seva is also performed as a form of ego-transcending spiritual practice known as sādhanā, and plays a large role in modern Hinduism. A key concept in Hinduism is liberation (moksha) from the cycle of births and deaths (saṃsāra), and sādhanā is the effort one makes to strive for liberation; this highlights the importance of service to others.
In Sikhism, the word seva also means "to worship, to adore, to pay homage through the act of love." In the writings of Sikh gurus, these two meanings of seva (service and worship) have been merged. Seva is expected to be a labour of love performed without desire and intention, and with humility.
Kar seva (Gurmukhi: ਕਰ ਸੇਵਾ), from the Sanskrit words kar, meaning hands or work, and seva, meaning service, another concept of Sikhism, is often translated as "voluntary labor". A volunteer for kar seva is called a kar sevak (voluntary laborer)—someone who freely offers their services to a religious cause. Sikhs use the term kar sevak to represent people who engage in ministrations, altruistic philanthropy, and humanitarian endeavors in service to religion and society. Sevadar (Punjabi: ਸੇਵਾਦਾਰ; also transcribed as sewadar), literally "seva-supporter", is another Punjabi word for a volunteer who performs seva.
The idea of selfless service (seva) is an important concept in several religions because God is perceived as having an interest in the well-being of others; serving other people is considered an essential devotional practice of indirectly serving God and living a religious life that is a benefit to others. People of every religion are included in this service.
In Hinduism, seva is the concept of service to God and/or humanity, without the expectation of return. According to Hindu scriptures, seva is seen as the highest form of dharma (righteousness). Seva has been said to provide good karma which facilitates the atma (soul) to obtain moksha (emancipation from the cycle of death and rebirth). Before the early nineteenth century, the meaning of seva (serving or honoring) had been virtually synonymous with that of puja (worship), which typically also included distribution of prasad (sacrificial offerings) such as food, fruits, and sweets to all gathered. Thus, seva typically involved offering of food to a deity and its murti (idol), followed by the distribution of said food as prasad. The concept of seva and karma yoga is explained in the Bhagavad Gita, where Krishna expounds on the subject. In modern times, the concept has been taken to volunteering for the greater good, such as in disaster relief and other major incidents.
Seva in Sikhism takes three forms: tan (Gurmukhi: ਤਨ), meaning physical service, i.e. manual labour, man (Gurmukhi: ਮਨ), meaning mental service, such as studying to help others, and dhan (Gurmukhi: ਧਨ), meaning material service, including financial support. Sikhism stresses kirat karō (Gurmukhi: ਕਿਰਤ ਕਰੋ), "honest work", and vaṇḍ chakkō (Gurmukhi: ਵੰਡ ਛਕੋ), "split up", sharing what you have by giving to the needy for the benefit of the community. It is a duty of every Sikh to engage in seva wherever possible, such as volunteering at a Gurdwara, community center, senior living centers, care centers, sites of major world disasters, etc. Seva can also be performed by offering service for a religious cause, such as constructing a gurdwara, a place of worship that performs community services such as providing volunteer-run food kitchens.
Kar seva is one of the main teachings of Sikhism—including its ordained philosophy, in Sikh scripture, theology, and hermeneutics. A tradition set forth with the clear understanding that there is God within all of us, and thus by serving humanity, you are serving God's creation. Seva is believed to be a way to control inner vices and is a key process in becoming closer to God.
Some Kar Seva groups and organizations have been criticized for their lack of care for and apathy towards preserving historical Sikh heritage sites, artwork, and architecture during renovation and construction projects. Large amounts of historical Sikh scriptural manuscripts have been systematically "cremated" (burnt to destruction) over the years at secretive ‘Angitha Sahib’ gurdwaras in Dehradun and around India as part of kar seva. The logic behind these crematoriums is the Sikh philosophy handed down by the tenth Guru Gobind Singh that Guru Granth Sahib is the living embodiment of a Guru, and so Sikh funeral rites are carried out. This practice is heavily criticized for systematically destroying historical manuscripts.
