Dasvandh or Dasaundh, literally means a "tenth part" and refers to the practice among Sikhs of contributing in the name of the Guru one-tenth of their earnings towards the common resources of the community. This is their religious obligation — a religious requirement or duty; a form of seva or humble service which is highly valued in the Sikh system. The concept of dasvandh was implicit in Guru Nanak’s own Gurbani in the line: "ਘਾਲਿ ਖਾਇ ਕਿਛੁ ਹਥਹੁ ਦੇਇ ॥ ਨਾਨਕ ਰਾਹੁ ਪਛਾਣਹਿ ਸੇਇ ॥੧॥ One who works for what he eats, and gives some of what he has - O Nanak, he knows the Path (1)" (SGGS p 1245) The idea of sharing and giving is symbolized by the institutions of langar (community kitchen) for the sangat (holy assembly) that the Guru has established.
