The Sun, of which we say, outwardly speaking, that it sends its light to the Earth, is not merely a radiant globe of gas but infinitely more than that. It sends its rays down to the Earth but whenever we look at the Sun it is the outer side of the rays that we see. The rays have, however, an inner side. If someone were able to look through the Sun’s light, to regard the light only as an outer husk and look through to the soul of it, he would behold the Soul-Power, the Soul-Being of the Sun. With ordinary human consciousness we see the Sun as we should see a man who was made of papier-maché.
An effigy in which there is nothing but the form, the lifeless form, is of course something different from the human being we actually see before us. In the case of the living human being, we see through this outer form and perceive soul-and-spirit. For ordinary consciousness the Sun is changed as it were into a papier-maché cast. We do not see through its outer husk that is woven of Light.
