DONATION
Dasvandh (Punjabi: ਦਸਵੰਧ, lit. ‘tenth part’,also transcribed as daswandh) is the one tenth part (or 10%) of one’s income that one should donate, both financially (as a tithe) and directly in the form of seva, according to Sikh principles.

It falls into Guru Nanak Dev‘s concepts of Vand Chhako and Kirat karo. The practice was followed during the period of Guru Arjan Dev and many Sikhs still continue to carry out the practice in the present-day.[6][5] The concept of dasvandh was implicit in Guru Nanak‘s own line: “ghali khai kichhu hathhu dei, Nanak rahu pachhanahi sei—He alone, O Nanak, knoweth the way who eats out of what he earneth by his honest labor and yet shareth part of it with others” .The idea of sharing and giving was nourished by the institutions of sangat (holy congregation) and langar (community kitchen) the Guru had established. Sikhs believe that whatever one gives in charity, they shall receive back many fold to their benefit in-return in both a material and spiritual sense, as the two realms are inseparable as per Sikh theology.
