Satisfying oneself is the toughest thing ever. People say its not easy to live to people's expectations , societies diplomacy, but what I feel that for once there mouth can be kept shut if one is satisfied or well settled or composed. I think people who realized this initially are the one who came up with all these concepts of meditation, self realization.
Was Buddha the one who realized this concept for the first time or it existed some more centuries back. whatever , it doesn't matter from where this very concept has rolled upon the important fact is the realization of this.
