Between birth and death he is plunged into a certain environment through having an etheric and physical body. He draws his food from the lower kingdoms of nature, these give him the substances and forces which pass through him. We might say that up to the time of birth he evolves, and then, on entering earthly existence, he comes in contact with the lower kingdoms of nature. It is true he only enters these when he takes on a physical body, and has then to assimilate them as his means of support; in the physical world man is not an absolute being. Only think how he must continually inhale a certain quantity of air; so that he is by no means enclosed within his skin, his being extends into the air. On entering physical existence he enters into a certain relationship with the kingdoms below him; he dips into them; on leaving his body he rises into higher kingdoms, into that of the Angels, Archangels, and Archai, and indeed into still higher kingdoms. Just as through the needs of his physical body he enters into relationship with the lower kingdoms, so after death he enters into relationship with higher kingdoms.
