Lecture II
There you see these four group-souls emerging from an indefinite background, the rainbow surrounding it and the number twelve. Now we must understand what this number twelve signifies. When that which has just been described is seen coming forth, there is a clairvoyant feeling that it is surrounded by something of an entirely different nature from that which emerges from the indeterminate spiritual. In ancient times that by which it is surrounded was symbolized by the Zodiac, by the twelve signs of the Zodiac. The moment of entering into spiritual vision is connected with many other experiences. The first thing perceived by one whose etheric body goes forth is that it seems to him as if he grew larger and larger and extended himself over what he then perceives. The moment comes when the initiate says: “I do not merely see these four forms, but I am within them, I have expanded my being over them.” He identifies himself with them. He perceives that which is symbolized by the constellations, by the number twelve. We shall best understand that which spreads itself around, that which reveals itself, if we remember that our earth has passed through previous incarnations. We know that before the earth became earth it went through the condition of Saturn, then through that of Sun, then through that of Moon, and only then did it become our present earth. This was necessary, for only in this way was it possible for the beings we see on the earth around us to come forth as they have done. They had gradually to work through those changing forms.
