Now you may ask: "In what way does one attain to spiritual knowledge by repetition? Is it by repeating the name of God that one comes to spiritual knowledge?" Not necessarily, but by repeating a certain thing you forget yourself. Forgetting yourself, you are forgetting the false self, and it is in forgetting the false self that lies the secret of spiritual attainment. Spiritual attainment apart, even the secret of the great works of musicians and poets was that they forgot themselves in their work. In order to give life to something one must make a sacrifice, and in spiritual attainment it is by the sacrifice of the false self that one comes to the real self.
