Langar was first started by Baba Farid, a Muslim of the Chishti Sufi order.[6] It became a common practice amongst Sufi Muslims in South Asia and it was later adopted by Sikhs. In Sikhism the practice of the langar, or free kitchen, is believed to have been adopted 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, a revolutionary concept in the caste-ordered society of 16th-century India where Sikhism began. In addition to the ideals of equality, the tradition of langar expresses the ethics of sharing, community, inclusiveness and oneness of all humankind. "...the Light of God is in all hearts."[7]
After the Second Sikh Guru, the institution of langar seems to have changed,[8] somewhat, and meat seems to have been excluded from this institution. The reason cited for this by historians is the accommodation of Vaishnavite[9] members of the community
