Lecture IV
Our conception of the state of sleep is, as a rule, too simple; and that is quite comprehensible because usually we describe things from one point of view only, whereas when a human being passes into the higher worlds conditions are complicated. A complete picture becomes possible only as we progress patiently in Spiritual Science and learn to view things from all sides. We generally characterise the state of sleep—and rightly so—by saying that the physical and etheric bodies remain in the bed, while the Ego and astral body move outwards and unite with the forces of the stars. But correct as this is from one point of view, it nevertheless presents only one aspect of the matter, as we can realise if we consider from the standpoint of Spiritual Science the sleep that occurs at a more or less normal time. Objectively speaking, an afternoon nap is a quite different matter from ordinary sleep at night. What I have now said is concerned not so much with a man's ordinary state of health but rather with his whole relationship to the world. We will therefore not consider an afternoon nap but the sleep of a healthy human being, let us say at midnight, regarded from the standpoint of clairvoyant consciousness.
