You are not your mind

Tolle describes how, at twenty-nine, after years of anxiety and depression, he went through a sudden inner shift. He woke the next morning into a deep peace that stayed with him, and the book grew out of what he learned from it.

His core idea is that most people are trapped in compulsive thinking. A voice in the head comments, judges and worries without pause, and we mistake that voice for who we are. Freedom begins when you watch your thoughts like an observer. In that moment you notice that you are the awareness behind the thinking, not the thinking itself.
