Every gurdwara keeps a langar, where volunteers prepare a vegetarian meal served free to anyone, regardless of religion, caste or status. Diners sit side by side on the floor. The custom began with Guru Nānak and was made a rule by Guru Amar Dās, who is said to have asked even the emperor Akbar to eat in the langar first.
