दातव्यमिति यद्दानं दीयतेऽनुपकारिणे
देशे काले च पात्रे च तद्दानं सात्त्विकं स्मृतम्

deshe kaale cha paatre cha taddaanam saattvikam smritam
That which is donated knowing that charity is duty, to whom one is not obliged, in the right place and time, to a worthy person, that charity is called saattvic.
