IX. Pictorial Representations as a Necessary Educational Tool for Mental Training

If we look at the plant in its original chaste substance, we find green as the color in the life of the plant. The plant is permeated by chlorophyll, by what is called chlorophyll, in those parts where the etheric body is actively alive. The etheric body has a basic law, which is the law of repetition. If only the etheric body were active in the plant, then one and the same form would be repeated again and again; leaf by leaf it sets in. But when the astral body of the earth begins to affect the plant, it completes growth and sets in the flowering. The effect of the etheric body is revealed in the repetition. This principle also applies to human growth. The etheric body shows its influence in the formation of the spinal vertebrae, but this only goes as far as the arching of the cranial vault, where the astral body begins to take effect. We can therefore only influence the etheric body through the principle of repetition. When you think and comprehend, you only affect the astral body. But when you pray or meditate, for example, and repeat the same prayer or meditation every day, you have an effect that extends into the etheric body. The way it is in the cosmos is that the principle of repetition first manifests itself in the deeds of the etheric body, then the principle of closure through the astral body. Where the astral body withdraws, the principle of repetition naturally reappears. This is how your hair and nails grow, because the astral body has withdrawn there. It doesn't hurt when you cut your hair, because pain is an expression of the astral body.
