Cosmic Ego and Human Ego
We distinguish then two classes of these Moon beings: First, those who had developed only their fifth principle, so that they were as we human beings would be if we should develop the Spirit-Self in the sixth post-Atlantean epoch, and then stop, and not develop the sixth and seventh principles. Let us keep in mind this one class, who as Luciferic beings had developed their fifth principle; and then note another class of Moon beings of the Luciferic sort who had developed their sixth principle but not their seventh. There were such at the beginning of the Earth evolution, when man began the development of his ego. So we can ask: What was the situation as regards these beings at the beginning of the Earth evolution? There were beings there who eagerly expected to develop their sixth principle during the Earth evolution, beings of a Luciferic kind, who upon the Moon had evolved only as far as their fifth principle and wished to develop their sixth upon the earth. And there were beings of the second class, who had already developed their sixth principle on the Moon, and who wished to develop their seventh on the earth. They expected that of the Earth evolution. Then there was man, who came over with three principles, to develop his fourth.
