Lecture IV

Now that part of the Ego-aura which streams downwards and becomes dark and more or less opaque while the part streaming up wards is luminous and radiant—all this lower part is particularly exposed to the influence of Ahrimanic powers. The adjacent part of the astral aura is, on the other hand, particularly exposed to the Luciferic forces. The account that has been given—quite rightly from a certain standpoint—that the Ego and astral body leave the human being during sleep is, however, strictly true only as regards the upper parts of the Ego-aura and astral aura. It is not correct as regards the parts of the Ego-aura and astral aura which correspond more to the lower areas of the human figure, particularly the lower parts of the trunk. Actually, during sleep, these parts of the astral aura and of the Ego-aura are more closely bound up with the physical and etheric bodies than is the case during the waking state, and below they are denser, more compact.
