Every Sikh shrine has a religiously sanctioned moral and humanitarian obligation to serve and provide hospitality, provisions, nourishments and meals to any man, regardless of race, creed, religious profession, identification, or affiliation. At the Langar (the temple's community run free kitchen), food is served to all visitors regardless of faith, religion, or background. Only vegetarian food is served and people eat together as equals. The institution of the Sikh langar was started by the first Sikh Guru, Guru Nanak. It was designed to uphold the principle of equality between all people regardless of religion, caste, colour, creed, age, gender, or social status. In addition to the ideals of equality, the tradition of langar expresses the ethics of sharing, community, inclusiveness, and oneness of humankind.
