4. Dream Life
As I have already said, the astral body is that part of our being which actually opposes the laws of nature. From morning to night, from waking till going to sleep, we are subject to these laws—laws which in relation to space and time we can grasp through mathematics. When we sleep, however, we extricate ourselves both from the laws of nature and from the laws of mathematics—from the latter laws because our astral body has nothing to do with the abstractions of three-dimensional space. It has its own mathematics, following a straight line in one dimension only. I shall have to speak again about this question of dimensions. It is truly the astral body that releases us from the laws of nature, by which we are fettered between waking and sleeping; it is also the astral body that bears us into a completely different world, the super-sensible world.
