II. Impulses of Transformation for Man's Artistic Evolution I

But this acquisition of the upright posture is only the most striking of these phenomena. Whenever we lift a hand a similar process takes place. In our ego we can only contain the thought of lifting a hand; this thought must at once act upon the astral body, and the astral body transfers its activity, which lives in it as an impulse, to the etheric body. And what happens then? Let us assume that someone is holding his hand in a horizontal position. Now he forms the idea: I want to raise my hand a little bit higher. The idea, which in life is followed by the act of lifting the hand, passes over to the astral body; there an impulse arises and passes over from the astral body to the etheric body. And now the following happens in the etheric body: The hand is at first horizontal; then the etheric body is drawn up higher, then the physical hand moves, following what occurs first as a development of force in the etheric body. The physical hand follows the etheric.
