“Giving simply because it is right to give, without thought of return, at a proper time, in proper circumstances, and to a worthy person, is sattvic giving. Giving with regrets or in the expectation of receiving some favor or of getting something in return is rajasic. Giving at an inappropriate time, in inappropriate circumstances, and to an unworthy person, without affection or respect, is tamasic.”
(Giving should be a pure act, completely untainted by any expectation of any return. The purest type of giving is that motivated by a compassionate heart to those deserving of such giving and needing it).
