V. Concerning Reincarnation and Karma; Man's Astral Body and the Spiritual World; and Ahrimanic Beings

Moreover, we learn to know spiritual beings who bring about this independent life of the reflected image of the spiritual world. We feel them to be beings who belong to the world of the spirit with regard to their origin, but who have left the arena of that world, and sought their field of action in the physical world. We thus find ourselves confronting two worlds which act one upon the other. We will call the spiritual world the higher, and the physical world the lower.
