Lecture I

We know that our ego develops through three soul members or principles, through the sentient soul, the intellectual or mind-soul, and the spiritual or consciousness-soul. All the worlds that come within the compass of these three soul members are also concerned with our ego. In the course of our Earth-evolution these three soul members first prepared for themselves the three external bodily members—the physical body, the etheric body and the astral body—through long Earth periods. In successive post-Atlantean epochs of civilization the three soul principles developed further, and in future Earth periods they will again adapt themselves to the astral, etheric and physical bodies, so that the Earth can be prepared to pass over to the Jupiter evolution.
