Lecture VIII

From a specific point of time between death and rebirth, therefore, a human being is already concerned with the preparation of his later earthly existence. The physical body which a man has on Earth does not by any means derive in all details from the physical lives of his ancestors, nor indeed from processes that can operate on the Earth. The physical body we bear is in itself fourfold. It has evolved through the periods of Saturn, Sun, Moon and Earth. Its very first foundation was laid during the Old Saturn period; during the Old Sun period the etheric body was woven into this foundation; during the Old Moon period the astral body was added and then, during the Earth period, the Ego, the ‘I’. As a result of these processes the physical body has undergone many changes. Thus we have within us the transformed Saturn foundation, the transformed Sun and Moon conditions. Our physical human body is the product of transformed physical conditions. The only part of all this that is visible is what has come from the Earth; everything else is invisible. Man's physical body is visible because he takes in the substances of the Earth, transforms them into his blood and permeates them with something that is invisible. In reality we see only the blood and what has been transformed by the blood, that is to say, a quarter of the physical human body; the other three-quarters are invisible. In the first place there is an invisible framework containing invisible currents—all this exists in the form of forces. Within these invisible currents there are also the influences exercised by one current upon another. All this is invisible. And now this threefold entity is filled out, permeated by the foodstuffs that have been transformed into blood. It is through this process that the physical body becomes visible. And it is only when we come to deal with the laws governing this visible structure that we are in the earthly realm itself. Everything else stems from cosmic, not from earthly conditions and has already been prepared when, at the time of conception, the first physical atom of the human being comes into existence. Thus what is later on to become the body of the human being has been prepared in past ages without any physical connection with the ultimate father and mother. It was then that the qualities transmitted by heredity were first worked into the process of development.
