12. Occult Development
Astral consciousness is four-dimensional in certain connections. In order to form an approximate idea of this, the following may be said. Anything that is dead has the tendency to remain in its three dimensions. Anything living extends all the time beyond the third dimension. Anything that grows has, through its movement, the fourth dimension within its three dimensions. If something moves in a circle, and if the circle it traces goes on increasing in size, we come at last to a straight line. But the straight line will not return to its starting point, because our world is three-dimensional. In astral space, a line does return, because astral space is closed on all sides. It is quite impossible, there, to go straight on for ever. Physical space is open to the fourth dimension. Height and breadth are two dimensions; the third dimension leads out into the fourth. In astral space a different geometry prevails.
