The talk in the back of my mind, from a piece in Provocations:
I was struck by the revelation that I have an unceasing inner voice that chatters a non-stop monologue in the back of my mind. Now some of you may be thinking, “I don’t know what you are talking about; I don’t have an unceasing inner voice.” That’s it—that’s the voice. At night we call it dreaming. In the day we can recognize it as worry, or the sub-vocalization of a frenzied and ever-changing personal focus. But what Lawrence learned to do was to move that voice from a monologue to a dialogue with God.
