V. Higher Worlds and Their Connection with Ours
People usually do not understand the change between waking and sleeping deeply enough. It is such an everyday occurrence that it hardly deserves attention. As a result, the mystery that these processes hold is completely lost on them. When asked what happens to a person when they fall asleep, one would receive the answer: Consciousness extinguishes, the tired brain falls into a state of stupor and no longer absorbs sensory impressions from the outside world. This is correct insofar as it refers to what can be perceived with the physical eye. However, if we ask the clairvoyant what he perceives, he will tell us that something very significant is taking place. He sees how the inner, astral man rises out of the resting physical body and pours into the astral world body, the macrocosm. And in the morning, upon awakening, he sees how that which has flowed into the universe contracts again and is absorbed by the physical body, the microcosm. He beholds the changing life that man leads in the world at large and in the world of small things.
