Langar is one of the most sacred and important aspects of Sikhism. The word langar simply means community eating place in Gurudwara (Sikh temple) where free food is served to all devotees and visitors without distinction of religion, caste, gender, economic status, or ethnicity. The free meal is always vegetarian. People sit on the floor, eat together, and the kitchen is maintained and serviced by community volunteers. The langar concept is a symbol of equality introduced first by the first Sikh Guru, Guru Nanak.. The second Guru of Sikhism, Guru Angad is remembered in Sikh tradition for systematizing the institution of langar in all Sikh temple premises, where visitors from near and far, could get a free simple meal in a communal seating. At the Golden Temple nearly 100,000 people dine every day in its langar. Source: Wikipedia
