V. Illness and Death

Today we shall speak, mainly from the physiological viewpoint, about the work the physical principle accomplishes on a person's organism between birth and the change of teeth. During this period, the physical principle works on the physical body, just as before birth the forces and substances of the maternal organism work on the embryo. From the age of seven till puberty it is mainly the etheric principle that works on the physical body; after puberty it is mainly the forces of the astral body that are at work. Thus, we must think of the human embryo being enveloped by the maternal body up to the moment of birth; at that point the maternal body is, as it were, pushed aside; the senses are freed; the outer world begins to influence the human organism. Then at the age of seven another enveloping sheath is pushed aside. The development of an individual's being can only be understood when we recognize that at the change of teeth something happens spiritually that is similar to what happens physically at birth. The human being is truly born a second time about the seventh year, for the ether body is born and can begin to work independently, just as was the case with the physical body at its birth. The maternal body acts physically on the embryo before birth; up to the change of teeth the spiritual forces of the ether world act on the human ether body. At about the seventh year they are pushed aside, as was the maternal body at physical birth. Up to the seventh year the ether body remains latent within the physical body. At the time of the change of teeth the situation in regard to the ether body is comparable to a piece of wood being ignited. Up till then it was tied to the physical body; now it is freed and can act independently. The ether body's release is announced by the change of teeth. Those with deeper insight into human development recognize that the change of teeth is a significant event. Up to the age of seven the physical principle is at work unfettered, while the etheric and astral principles are still latent, that is, not yet born from their spiritual sheaths.
