III. The Elemental World and the Heaven World. Waking Life, Sleep and Death.
Firstly, there is a region which may be compared with solid, physical regions: it is the Continental region of Devachan. What is physical here on the earth is, in this region of Devachan, found to be a multitude of spiritual Beings. Think, for example, of a physical human being. To devachanic vision he appears like this: what the physical senses perceive, vanishes, and light flashes up in the sphere immediately around the physical man, where otherwise there is a void; in the middle, where the physical body is, there is an empty, shadowy space—like a kind of negative. Animals and human beings appear here in negative pictures; blood appears as green—its complementary colour. All formations which are physical in our world are present in the Archetypes of Devachan.
