The field of the inner life of man allows us, as nothing else does, to penetrate it with our own intuitive experience. For we ourselves are always in some sense the cause of the events that take place there. In order to make observations in this region, however, we need to bring about a certain awakening in a part of our being which - so long as we rely on the purely natural forces of our body - remains sunk in more or less profound unconsciousness.
