We must not imagine that the reflection of the Universe which we see when we speak so the starry world from the earthly point of view, is also the view presented to our super-sensible perception between death and rebirth. That which appears simply externally to us here on Earth as the starry world, then reveals itself in its nature, in its Spiritual being. We have then to do with the inner aspect of what, while we are on Earth, simply reveals its external aspect. Indeed we must admit that both when we look down on to the Earth as will as when we look up to the Cosmos, in so far as we are dealing with a sense impression we always have a sort of illusion before us; and we only come to the truth when we can penetrate to those Beings who lie at the bottom of this illusion, with their various degrees of Cosmic self-consciousness.
Whether man looks up or down, I must therefore call it illusion; the truth, the Being, lies behind this illusion.
