There are two sheer dynamic principles in our universe, the sun-principle and the moon-principle. And these principles are known to us in immediate contact as fire and water. The sun is not fire. But the principle of fire is the sun-principle. That is, fire is the sudden swoop towards the sun, of matter which is suddenly sun-polarized. Fire is the sudden sun-assertion, the release towards the one pole only. It is the sudden revelation of the cosmic One Polarity, One Identity.

But there is another pole. There is the moon. And there is another absolute and visible principle, the principle of water. The moon is not water. But it is the soul of water, the invisible clue to all the waters.

So that we begin to realize our visible universe as a vast dual polarity between sun and moon.
