2. Human Duality

Imagine to yourselves the different sense-impressions that stream into us; imagine these contracted, thickened or condensed, formed into organs and placed inside us. Thus the blood presents itself inwardly to the liver, gallbladder and spleen, in the same way as the upper part of the human organism presents itself to the outside world. And so we have the outside world which surrounds our sense-organs above, condensed as it were into organs that are placed in the interior of man, so that we may say: At one moment the world is working from outside, streaming into us, coming into contact with our blood in the upper organs, acting upon our blood; and the next moment that which is in the macrocosm works mysteriously in those organs into which it has first contracted itself, and there, from the opposite direction, acts upon our blood, presenting itself again in the same way as it does in the upper organs.
