Even for becoming a member of any institution or organization, the query is "What are the benefits that one can derive by being a member?" But here there are no benefits for whatever one offers.
One may surrender everything that one possesses; still one does not expect any return whatsoever. On the contrary, one is bashful or feels dejected that one can give only this much that one possesses, when there is a need to give more. With the maximum giving one is still unhappy that one is not in a position or is not able to satisfy the requirement of the people. And this discontent, of course a noble discontent, urges one to utilize all one's potentialities and to find new avenues from where one can acquire more, just only for giving more. Such giving is an absolute giving, and not a relative giving.
