My question is what is the importance of gaining knowledge, without any materialistic interest, and just for the sake of gaining knowledge. If a very knowledgeable person has no wealth, fame, power and any other materialistic plus point, still can he say that he's successful just and just because he has knowledge? For example if a person, Mr. A, led all his life in the pursuit of knowledge, just because of his curiosity, and earn no money, fame, power; he didn't convey his learnings to anyone by writing or any other means. He got no self satisfaction by knowing that he has become a great scholar (because to him there are tooooo many things he don't know even then). And in this pursuit he died. Can we say that Mr. A led a successful life?
