VII. Inner Processes in the Human Organism. Sense-Perception, Breathing, Sleeping, Waking, Memory

In the book Occult Science, I have called the world that man learns to know by thus withdrawing his attention from the outer world and living within his own senses, the world of the Angeloi, the Beings who stand one stage higher than man. What is it that actually happens in our senses? We can fathom it if we are able to observe the inner activity of the senses while we are not actually perceiving with them. Just as we can remember an experience that took place years before, although it is no longer present, so, if we are able to observe the senses while they are not engaged in any act of perception, we can acquire knowledge of what happens there. It cannot be called remembrance, for that would convey a fallacious idea; nevertheless, in what we perceive we can at the same time perceive the processes that are engendered in the senses by the outer world through color, sound, smell, taste, touch, and so forth.
