"You think and talk too much," he tells the apprentice. "You must stop talking to yourself....Think about it. Whenever you are alone, what do you do?" Castaneda replies that he talks to himself - about anything. Don Juan says,I'll tell you what we talk to ourselves about. We talk about our world. In fact we maintain our world with our internal talk.... Whenever we finish talking to ourselves the world is always as it should be. We renew it, we kindle it with life, we uphold it with our internal talk. Not only that, but we also choose our paths as we talk to ourselves. Thus we repeat the same choices over and over until the day we die, because we keep on repeating the same internal talk over and over until the day we die. Every one of us does that. a separate Reality - Carlos Castaneda
