Verse
दातव्यमिति यद्दानं दीयतेऽनुपकारिणे ।देशे काले च पात्रे च तद्दानं सात्त्विकं स्मृतम् ॥
The sattwic way of giving is to do it for the sake of the giving and the beneficence and to one who does no benefit in return; and it is to bestow in the right conditions of time and place and on the right recipient (who is worthy or to whom the gift can be really helpful).
