XXV. Man's Life in the Light of Occult Science
At first this may seem like a gray theory, but it is not. Only those who know that physical life is born at the time of physical birth and that the etheric body is only present at the change of teeth, only then does this etheric body freely face the world, can unfold principles for the education of the child. Now we present what follows from this: as long as the human germ is in the mother's womb, it does not come into contact with external light or external influences. This would be impossible, otherwise the germ would be destroyed. They have to wait to influence the light until the eyes, until the person is born. Every materialistically thinking person can see that. But they do not know that it is just as bad for the spiritual person to allow influences to flow into the etheric body that should only flow in after the change of teeth, when the etheric body is exposed on all sides. This means nothing other than that we have to base our educational principles on this.
