Lord Krishna had said  It means that a donation that is made as a duty without expecting anything in return and if that donation is made at the right place, right time and to the apt person is known as Satvik daan or a virtuous donation
दातव्य मिति यद्दानम् दीयते नुपकारिणे ।देशे काले च पात्रे च तद्दानं सात्त्विकं स्मृतम्‌ याचा अर्थ असा की, कोणत्याही उपकाराच्या भावनेशिवाय, योग्य ठिकाणी योग्य वेळी योग्य व्यक्तीला जे दान दिले जाते त्याला सात्विक दान म्हणतात.
