"The ego is created by the rift. When you are fighting, the ego comes in; when you are not fighting, the ego cannot come in. Ego is a tension. If you want the ego, then divide yourself as fully as possible - become two persons. That is what is happening to many people, that is what has happened to whole of humanity. Everybody has become two persons: one voice says "Do this," the other voice says "Don't do that" - then the ego arises. Out of friction ego arises, and ego is very intoxicating; it makes you unconscious. This is the whole mechanism."
