Chapter III: Sleep And Death
Whatever assumes physical form upon Earth and is thus made perceptible to physical organs, is seen in its spiritual essence in the first region of Spirit-land. For example, one may there perceive the power which builds the form of a crystal. Only what there reveals itself is like the antithesis of what appears to the senses in the outer world. The space which is here filled by the rocky material appears to the spiritual eye as a kind of hollow or vacuum; while all around the hollow space is seen the force building the form of the stone. The characteristic color which the stone has in the sense-world is experienced in the spiritual world as its complementary. Seen therefore from Spirit-land, a red stone is experienced with a greenish and a green stone with a reddish hue. Other properties too appear as their antithesis. Even as stones, rocks and geological formations constitute the solid land—the continental region—of the world of Nature, so do the entities we have been describing constitute the “solid land” of the spiritual world.
