XI. Concerning Beings of the Spirit-Worlds

If man observes what these beings experience through their etheric bodies, he finds that their experiences are similar to those of his own soul. They have thinking power; they have feelings and a will. But through their etheric body they develop something which man can only develop through the physical body. Through their etheric body they arrive at a consciousness of their own being, although man would not be able to know anything about a supersensible being unless he carried up into supersensible worlds the forces which he acquires in the physical body.
