There are times when you don't know yourself. There are times when you don't want to know yourself. There are times when you want to be what you have never allowed yourself to be before.
So you have to be your own teacher and your own disciple, and there is no teacher outside, no saviour, no master; you yourself have to change, and therefore you have to learn to observe, to know yourself. This learning about yourself is a fascinating and joyous business.
