The seeing commit a strange error. They believe that we know the world only through our eyes. For my part, I discovered that the universe consists of pressure, that every object and every living being reveals itself to us at first by a kind of quiet yet unmistakable pressure that indicates its intention and its form. I even experienced the following wonderful fact: A voice, the voice of a person, permits him to appear in a picture. When the voice of a man reaches me, I immediately perceive his figure, his rhythm, and most of his intentions. Even stones are capable of weighing on us from a distance. So are the outlines of distant mountains, and the sudden depression of a lake at the bottom of a valley.
