Lecture II

Furthermore, when we come to the airy nature of the human being, it appears that the gases filling his being are in a state of perpetual interchange with each other. In the course of these lectures we shall have to show that this is neither an inorganic interchange nor merely a process of interchange mediated by the solid organs, but that an individual lawfulness controls the inner interchange of the gases in the human being, the vortex formed with the interworkings of the gases. Just as there is an inner lawfulness in the solid substances, expressing itself, among other things, in the relationship between the kidneys and the heart, so we must postulate the existence of a lawfulness within the airy or gaseous organism—if I may use this expression—a lawfulness that is not confined to the physical, solid organs. Anthroposophy designates this lawfulness that directly underlies the airy or gaseous organism as the astral lawfulness, the astral organization. This lawfulness would not be there in the human being if his airy organization had not permeated the solid and fluid organizations. The astral organization does not penetrate directly into the solid and the fluid. It does, however, directly lay hold of the airy organization. This airy organization directly takes hold of the solid and fluid, so that in the airy human being there is now an organized astral organization by which this airy organization has a definite inner form, which is naturally fluctuating.
