Langar (Sufism)
Langar (Persian: لنگر) is an institution among Sufi Muslims in South Asia whereby food and drink are given to the needy regardless of social or religious background. Its origins in Sufism are tied to the Chishti Order. Etymology
Langar is originally a Persian word, and later came into Urdu and Punjabi from it, and in Bengali as longor (). Religious meaning

Serving food to the needy has been a rich tradition among Sufis, especially of the Chishti Order. There is extensive use of free food imagery and metaphor in Sufi writings. Sugar and other sweet foods represent the sweetness of piety and community with God, while salt symbolizes purity and incorruptibility. The transformation of the raw wheat to finished bread is used as an analogy for Sufi spiritual development. Sufi ritual observances (dhikr) are concerned with remembrance of God through exaltation and praise. Singing, dancing, and drumming are commonly part of such rituals, as is sharing of food. The tradition of langar was also adopted by the Sikh community, where it goes by the same name. Langar khana
