to speak, mirrored themselves in man. This was indeed the mission of the
human senses at that time. It has already been shown that the senses did
not as yet transmit objective perceptions. But they reflected the nature
of the Sons of Life. What those Sons of Life perceived through reflection,
gave them their "ego-consciousness." What was aroused in the human astral
body by this reflection was the dull dim pictures of the
Moon-consciousness. By thus acting conjointly and reciprocally with the
Sons of Life, the human beings laid the foundations of the nervous system
within their physical bodies. The nerves appear, one might say, as
continuations of the senses, directed inwardly into the human body.

It is evident, from this description, in what manner the three kinds of
Spirits, those of Personality, of Fire, and of Life, act upon
Moon-humanity. If we look back upon the most important, namely the middle
period of the Moon evolution, we may say that the Sons of Personality are
at that time implanting in the human astral body independence and the
character of personality. It is owing to this fact that man can turn his
attention inwards and work upon himself during those times when the Sun is
not shining upon him.

The Sons of Fire act upon the etheric body in so far as the independent
formation of the human being becomes imprinted upon it. Through their
means it comes to pass that human beings are again conscious of
themselves, as such, every time the body is renewed. Thus a kind of memory
is bestowed on the etheric body through the Sons of Fire.

The Sons of Life act on the physical body in such a way that it is able to
become the expression of the astral body which has now become independent.
They thus make it possible for the physical body to become a physiognomic
copy of its astral body. On the other hand, higher spiritual beings, in
particular the Lords of Form and of Motion, reach down into the physical
and etheric bodies, as far as these are developing during the Sun periods,
regardless of the independent astral body. Their intervention comes from
the Sun, in the manner described above.

Under the influence of such facts, the human being gradually matures to a
point where it can develop within itself the germ of the Spirit-Self just
as during the second half of the Saturn evolution it developed the germ of
the Spirit-Man and on the Sun that of the Life-Spirit. Thereby all the
Moon conditions are changed. Human bein
