I have been reading a book named 'Living with Himalayan Masters' in which the author's guru asks him to think on this:
"What did you learn on your own?
Whatever you learnt is from your parents, then teachers, friends, books..everything handed over from somebody else.
Everything you learnt is a second-hand knowledge?
Did you discover anything on your own?
Did you add some knowledge by yourself?
Learning by experiencing is the only real knowledge.
You will be a master of that. You will not forget that."
I have been thinking over this. Now, you also do.
