Amongst all the relationships which man has to the external world, the most important of all is breathing. We begin breathing the very moment we enter the physical world. Breathing in the mother-body is, if I may put it so, a preparatory breathing: it does not yet bring into being a complete connection with the external world. The child only begins to breathe in the proper sense of the word when he has left the mother-body. Now this breathing signifies a very great deal for the human being, for in this breathing there dwells already the whole threefold system of physical man. You know that amongst the members of the threefold physical human system we reckon, in the first place, the digestion and metabolism. But the metabolism, the assimilation, is intimately connected at one end with the breathing. The breathing process is connected with the blood circulation through metabolism. The blood circulation receives into the human body the substances of the external world which are introduced by another path, so that on the one hand the breathing is connected with the whole metabolic or digestive system.

On the other hand the breathing is also connected with the nerve-sense life of man. As we breathe in, we are continually pressing the cerebro-spinal fluid into the brain: and, as we breathe out, we press it back again into the body. Thus we transplant the rhythm of breathing to the brain. And as the breathing is connected on the one hand with digestion and assimilation, so on the other hand it is connected with the life of nerves and senses. We may say: the breathing is the most important mediator between the outer physical world and the human being who is entering it. But we must also be aware that this breathing cannot yet, by any means, function so as fully to maintain the life of the body. This applies particularly to the one side of breathing. At the beginning of his physical existence man has not yet achieved the right harmony, the right connection between the breathing process and the nerve-sense process. Observation of the nature of the child will show us that he has not yet learnt to breathe in such a way that breathing maintains the nerve-sense process rightly. In this lies the finer characterization of what we really have to do with the child. We must first gain an Anthropological-Anthroposophical understanding of the human being. Thus the most important measures in education will consist in paying attention to all that rightly organizes the breathing process into the nerve-sense process. In the higher sense the child has to learn to take up into his spirit what is bestowed on him in that he is born to breathe.

This part of education will, you see, tend to the side of the soul and the spirit. By harmonising the breathing with the nerve-sense process we draw all that is soul and spirit into the physical life of the child.
