Death, Karma, and the Immortal Monad's Evolution
We have seen that the entire human body is put together, has been put together, out of parts which arose through the fact that the originally undifferentiated mass divided itself into organs, after the original astral body had thrown off various portions of itself which were then reflected back, causing images to arise within it.[^1] These reflected images became forces within the astral body and these built up the etheric body, that is to say, through these manifold images the etheric body developed separate members. This etheric body now consisted of different parts and, as a further process, each of these parts densified within itself and so the differentiated physical body developed. Every such physical kernel, out of which the organs later develop, forms at the same time a kind of central point in the ether.
