Lecture I

But this liquid that, as it were, radiates from the kidney system into the whole organism and also radiates into the eye, is by all means not a dead watery substance, but a living water. You would get a totally wrong idea of what the water (the watery) is in man, if you had the picture that within the living human organism, one might find water, as it runs in a brook (see diagram, blue). This is not the case. In the brook, we have dead water, in the human organism we have a living liquid. Not only the plasma-liquid is living, all that is liquid in the human body is living. And in this liquid there are finely dissolved those solid parts, mentioned before, which are carried forth as it were, on the waves of the watery, also up into the eyes. Two different things meet now in the eye, the etheric organism of man (blue) fills out the eye, which is the optic nerve of the eye; and what is streaming now into this liquid which is filled by the etheric organism,—that is the astral picture which arises in the human astral body (red). And this (yellow) is what arises through the ego. That is what streams into here, and also streams further on.
