IV. The Art of Education Consists of Bringing Into Balance the Physical and Spiritual Nature of the Developing Human Being

The value of these things will only be fully appreciated when one can perceive the wonderful structure of the human organism and its harmony with the universe, the cosmos. It is wonderful to think that what we have observed in a child's development between birth and puberty is an interplay between cosmic-formative ( plastiche>) and cosmic-musical forces. This interplay unfolds of course in the most diverse variations. And—I think, I have pointed to this important fact in various connections before, but I should like to mention it once more, because it can be very helpful here—if you look at the human constitution you will find on the one hand the physical body and the etheric body: these two never separate from each other between birth and death: in a certain way they are constantly united between birth and death. On the other hand, the physical body and the ether body separate from the astral body—first of all the ether body from the astral body—when one falls asleep and they join again when one wakes up. Thus we can see that the ether body and the astral body are less firmly bound to each other than, for instance, the physical body and the etheric body are; equally strongly connected, on the other hand, are the ego and the astral body which do not separate from each other while one is asleep. Well, what is man through his physical body here on earth? He is a being who lives in intimate interaction with the surrounding air. A certain quantity of air is at one moment in our body, at another outside it; we breathe in, we breathe out. This in and out breathing reveals in a delicate way the difference between man' 1, waking and his sleeping condition. There is a subtle difference and in matters of great importance the subtle differences are often more significant than others. What happens here takes place through interaction between the astral body and the etheric body. It takes place in waking man, and also when man is asleep. This interplay between the musical element and the formative element during man's formative years ( Entwicklungszeit) is the continual and mutual permeation of the vibrations of the astral body in which the ego participates and the vibrations of the ether body which are shared by the physical body. Fundamentally, in the morning man breathes in his ego and his astral body and on falling asleep he breathes them out again.
