Osho reveals the secret how he is able to talk.
Talking to you, I have to put my mind on, otherwise how can I talk? The heart cannot talk, the being cannot talk, the essence knows no language. I have to use the personality. But the moment I have said, “Enough for today,” you may not know but that is how I put it off.
I tell you the secret! It is not to you that I am saying enough for today; I am saying to my own mind, “Enough for today. Now go to sleep.”
