Daswand literally means a tenth part and refers the act of donating ten percent of ones harvest, both financial and in the form of time and service such as seva to the Gurdwara and anywhere else. It falls into Guru Nanak Dev's concept of kirat karo. This was done during the time of Guru Arjan Dev and many Sikhs still do it up to this day. The concept of dasvandh was implicit in Guru Nanaks own line: ghali khai kichhu hathhu dei, Nanak rahu pachhanahi seiHe alone, O Nanak, knoweth the way who eats out of what he earneth by his honest labour and yet shareth part of it with others. The idea of sharing and giving was nourished by the institutions of sangat (holy assembly) and langar (community kitchen) the Guru had established.
