Why should we have all these bitter experiences in order to gain faith in ourselves? We can see that all the difference between man and man is owing to the existence or non-existence of faith in himself. Faith in ourselves will do everything. I have experienced it in my own life, and am still doing so; and as I grow older that faith is becoming stronger and stronger. He is an atheist who does not believe in himself. The old religions said that he was an atheist who did not believe in God. The new religion says that he is the atheist who does not believe in himself.
