I think self-knowledge comes when you observe yourself in your relationship , with all the people around you; it comes when you observe the manner of another, his gestures, the way he wears his clothes, the way he talks, his contempt or flattery and your response; it comes when you watch everything in you and about you and see yourself as you see your face in a mirror. When you look into the mirror you see yourself as you are, don't you? You may wish your head were a different shape, with a little more hair, and your face a little less ugly; but the fact is there, clearly reflected in the mirror, and you can't push it aside and say, "How beautiful I am!" Now, if you can look into the mirror of relationship exactly as you look into the ordinary mirror, then there is no end to self-knowledge. it is like entering a fathomless ocean which has no shore. Most of us want to reach an end, we want to be able to say, "I have arrived at self-knowledge and I am happy; but it is not like that at all. If you can look at yourself without condemning what you see, without comparing yourself with somebody else, without wishing to be more beautiful or more virtuous; if you can just observe what you are and move with it, then you will find that it is possible to go infinitely far. Then there is no end to the journey, and that is the mystery, the beauty of it.Try it.
