Man is a machine, but a very peculiar machine. He is a machine which, in right circumstances, and with right treatment, can know that he is a machine, and having fully realized this, he may find the ways to cease to be a machine. First of all, what man must know is that he is not one; he is many. He has not one permanent and unchangeable โIโ or Ego. He is always different. One moment he is one, another moment he is another, the third moment he is a third, and so on, almost without end.
P.D. OuspenskyWhen a man begins to know himself a little he will see in himself many things that are bound to horrify him. So long as a man is not horrified at himself he knows nothing about himself.
P.D. OuspenskyIf a man gives way to all his desires, or panders to them, there will be no inner struggle in him, no 'friction,' no fire. But if, for the sake of attaining a definite aim, he struggles with desires that hinder him, he will then create a fire which will gradually transform his inner world into a single whole.
P.D. Ouspensky
