What builds man's ego is every kind of gratification of the ego, and what breaks the ego is patience and renunciation. The question whether it would be advisable to so destroy the ego that others might take advantage of a refined person is answered by saying that it is not necessary that one should work against the ego, but one must control it. It would not be exaggerated if I said that man's worst enemy is his ego, his own ego. And when it is not under his control man's thought, speech and action are bent towards the gratification of his ego, and the more he satisfies his ego the more his ego desires, and it is never satisfied. Nobody else has such power in life of enslaving a man as his own ego.
