A cat actually thinks visibly. If you watch him jump on a shelf, the wish to jump and the action of jumping are one and the same thing... It's in exactly the same way that all Brook's exercises try to train the actor. The actor is trained to become so organically related within himself, he thinks completely with his body. He becomes one sensitive, responding whole... The whole of him is one.
