Many people live with a tormentor in their head that continuously attacks and punishes them and drains them of vital energy. It is the cause of untold misery and unhappiness, as well as of disease. The good news is that you can free yourself from your mind. This is the only true liberation. You can take the first step right now. Start listening to the voice in your head as often as you can. Pay particular attention to any repetitive thought patterns, those old gramophone records that have been playing in your head perhaps for many years. This is what I mean by "watching the thinker," which is another way of saying: listen to the voice in your head, be there as the witnessing presence. When you listen to that voice, listen to it impartially. That is to say, do not judge. Do not judge or condemn what you hear, for doing so would mean that the same voice has come in again through the back door. You'll soon realize: there is the voice, and here I am listening to it, watching it. This I am realization, this sense of your own presence, is not a thought. It arises from beyond the mind.
— Eckhart Tolle
