The Power of Selflessness (Nishkamata)

Nishkamata or selflessness 

is a quality when a devotee does not care about his own pain to please Krishna. If he does something what Krishna wants, then Krishna becomes happy and that is what a devotee wants. This is a story of a Sadhu (hermit) who attempted to make Krishna happy. And the God who does not appear on hard austerities of sages was compelled to appear to keep the wish of his devotee.

Moral of the story:

This story was referred to by Jagadguru Shri Kripalu Ji Maharaj to explain how a devotee can get everything without asking for anything.

If a devotee does not care of his own pain to make Krishna happy, then Radha Krishna, the Yugal Sarkar become a slave to him.
