The caelum, then, is a condition of mind. Envision it as a night sky filled with the airy bodies of the gods, those astrological constellations which are at once beasts and geometry and which participate in all things of the world as their imaginal ground. The caelum does not of course take place in your head, in your mind, but your mind moves in the caelum, touches the constellations, the thick and hairy skull opens to let in more light, their light, making possible a new idea of order, a cosmological imagination whose thought accounts for the cosmos in the forms of images.
