world, which began to be
covered as with a veil between death and birth just as it is hidden from
physical vision upon earth.

The many changes which took place in the spiritual world while human
evolution was passing through the conditions just described, found
physical expression in the gradual adjustment of the mutual relations
existing between the sun, moon, and earth (and, moreover, between other
celestial bodies).

The alternation of day and night stands out as one result of those
relations. (The motions of celestial bodies are regulated by the beings
who inhabit them. The earth's motion, of which day and night are the
result, was induced by the mutual relations of various spirits superior to
man. The moon's motion had been brought about in the same way, in order
that after the separation of the moon from the earth, the Lords of Form
might, by means of the revolution of the former around the latter, work
upon the human physical body in the right way, and with the right rhythm.)
The ego and astral body of man now worked within the physical and etheric
bodies by day; at night that activity ceased: for the ego and the astral
body then left the physical and etheric bodies and came wholly within the
sphere of the Sons of Life or Angels, the Sons of Fire or Archangels, the
Sons of Personality, and the Lords of Form. Besides the Lords of Form, the
Lords of Motion, of Wisdom and the Thrones also included the physical and
etheric bodies in their sphere of influence at this time. The injurious
effects produced on man by the errors of his astral body during the day,
could thus be counter-balanced.

As people upon Earth now again multiplied there was no reason why human
souls should not incarnate in their descendants. The earth moon-forces now
acted in such a way that under their influence the human bodies became
entirely capable of incarnating human souls. The souls who had previously
removed to Mars, Jupiter and the other planets were now guided to earth,
and there was thus a soul ready for each human being born in the physical
line of descent. This went on through long periods so that the immigration
of souls to earth corresponded to the increase of human beings. Souls now
leaving their bodies at physical death retained the echo of their earthly
individuality as a memory in the disembodied state. This memory acted in
such a way that whenever a body was born on earth suitable for them, they
again incarnated it. Consequen
