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.
