27. Problems of Nutrition

Our attention has frequently been focused on how the ascent from the purely physical to the spiritual realm can be made. We have often heard that the physical body is sustained by the etheric body. This is the architect of the physical body, which must not be viewed as if only chemical processes took place in it. We will be wrong if, by observing only the chemical processes, we simply ask in a materialistic fashion what happens to the chemical substances. Beyond the etheric body, we must remember, is the astral body. Through it are expressed the instinctive feelings and in certain respects the various aspects of the soul. When we behold man from the standpoint of spiritual science, we find that his etheric body as well as his physical body are inter-penetrated by his astral body. We must not see only one side but also perceive the astral body beyond the physical. Added to these is the ego, the fourth member of the human being. We have the total man before us only when we see in him this fourfold being. Only with the total fourfold man before us can we do justice to the scope of the problem of nutrition. Only then can answers be given to the question of how these four members of man's organism react to the influences of various diets.
