When you don't believe something, you can't make yourself believe it. There's nothing you can do to believe it again. You either believe it or you don't.
Byron KatieIt's very benign, it seems, to think, "There's a tree." In fact, it's a very beautiful thought. If someone chops down all the trees, then we think, "Oh, my goodness, something is out of order in my world." We begin to think, "Who am I in a world without trees?"
