At night, then, we have the following condition: Just as the human physical body and the human etheric body are by day the bearers of the human ego and the human astral body — in other words, of the innermost principles — so by night they become the bearers, or the temple, of higher astral and ego beings. Now we look with different eyes at the sleeper, for the astral principle within him is a divine-spiritual principle, and there is also an ego, but a divine-spiritual ego. In a sense it can be said that while we are asleep in respect of our astral body and ego, we are watched over and the structure of our organization is maintained by these beings that thus become a part of our life, beings that enter our physical and etheric bodies when we ourselves abandon these. A great deal can be learned from a fact of this sort; and especially if taken in conjunction with certain clairvoyant observations it can elucidate much concerning the evolution of man. What we shall now do is to correlate this difference between waking and sleeping with the great spiritual facts of evolution.
Translator's Notes:2. In his translation of Occult Science, an Outline, by Rudolf Steiner, Mr. Henry B. Monges provided an ingenious device for eliminating the confusion that arises so easily in connection with the study of planetary evolution. The following footnote, quoted from Occult Science, explains it.In order to make clear the difference between the designations for the Planetary Evolutions and our present planetary bodies, which bear the same names, the following device has been determined on: Saturn, Sun, Moon, Earth, Jupiter, Venus, Vulcan printed in italics with initial capitals designate the great cosmic planetary cycles of evolution. In the Sun evolution, after the separation of the main cosmic body into two parts, the designation is Sun and Saturn, spelt with capitals, but not with italics. In the Moon evolution, when a separation takes place, the remaining body is spelt Moon, with an initial capital, the separating planetary sun is spelt with small letters. In the Earth evolution, the separated planetary bodies are spelt as is customary: The planets Saturn, Jupiter, Mars, Venus, Mercury with initial capitals; sun, moon, earth with small letters.”The device is gratefully adopted in this translation.
