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

As long as we feel ourselves to be in that world, we find ourselves completely outside the sphere in which all the experiences and events of the physical world are enacted. We look from another world back upon the one which we have in a certain sense left behind. But we also arrive at the knowledge that, as human beings, we belong to both worlds. We feel the physical world to be a kind of reflected image of the world of the spirit. Yet this image, although reflecting the events and beings of the spiritual world, does not merely do this, but also leads an independent life of its own, although it is only an image. It is as though a person were to look into a mirror, and as though his reflected image were to come to independent life whilst he was looking at it.
