You do not train your mind, you untrain your mind.
You untrain your mind by just observing your own thoughts, by watching yourself think, by not reacting to your thoughts, not reacting to what happens in your world. As you do this you begin to dissolve. You find peace. You find peace. You become free. You become love. You no longer talk too much. You no longer try to evaluate the world or your position. You no longer find fault anywhere. You become your own experience. You have expanded. You used to be concerned with yourself as a body, with your health, concerned with your affairs. But now even though you are involved in the world, you are not of the world. The world has no pull on you. The world cannot show you anything. It cannot do anything to you. The world is the same as your body. You are not the body, you are not the world, you are not your mind. You are something completely different. That something different is ineffable.
