9. The Sleeping-and-Waking Rhythm in the Context of Cosmic Evolution

There is one part of the human being—and this may surprise you—one part of the physical human being that basically is always asleep. These are things one need not necessarily go into at the very beginning-of one's anthroposophical life—the finer points of spiritual science can only come to our attention gradually. When it is said that man is awake in the daytime and asleep at night we naturally assume his ego and astral body to be fully united with the physical and ether bodies during the day whilst having a separate existence outside the physical and ether bodies at night. It is only gradually that we progress from a rough outline of the facts established through spiritual science to more specific truths. Very generally speaking, it is correct that during sleep man's ego and astral body are outside his ether and physical bodies. There is however a part of the body that is asleep also between waking up and going to sleep, at least essentially so. Oddly enough this is the part of the human body we call the ‘head’. This is asleep when we are awake. You might well think the head to be the part that is most awake. In reality, however, it is the least awake part of us. In his thinking activity, and in head work altogether, man is awake. This is only possible, however, because even when we are awake the relationship of the ego and astral body to the head organs is such that they—that is the ego part of the head, the astral part of the head—cannot unite completely with the physical and ether part of the head. They always experience a life of their own outside the physical and ether part of the head. They always experience a life of their own outside the physical and ether parts of the head, as it were. A close union between the astral and the physical parts of the head occurs only when we have a headache. If we have a powerful headache, the astral, physical and ether parts of the head are very much united. We are least able to think when we have a headache. The reason is that the bond between the astral, physical and ether parts of the head is too strong. Our thinking, in which we are awake, and all other waking soul life bases on the fact that the ego and astral body of the head are in a way outside the head and therefore reflected, mirrored, in the physical and ether body of the head. Similarly we are only able to see ourselves in a mirror because we are outside it. It is this mirroring effect that provides the images for everyday consciousness. Those are mirror images we experience and take note of in everyday life. Living thus outside the head, with the head asleep and ego and astral activity reflected back by the hard skull, we are able to feel the inner ego and the inner astral body to be our own. In the other parts of the body ego and astral activity are still influencing the activity of the physical and ether bodies to a much greater extent. If the same held true for the head we would be conscious of the activity of digestive organs, and perhaps also rhythmical activity like that of the heart, In our heads—or perhaps not be conscious of them—and there could be no question of thinking activity. Thinking depends on activity being reflected, thrown back, and absorbed. The heart and other organs with the ability to absorb take in ego and astral body activity. The organs of the head do not absorb it but rather reflect it; the result is that it can be experienced in the inner soul.
