It is not the sun which we see in heaven. It is the rushing thither and the rushing thence of the vibrations expelled by death from the body of life, and returned back again to the body of life. Possibly even a dead soul makes its journey to the sun and back, before we receive it again in our breast. Just as the breath we breathe out flies to the sun and back, before we breathe it in again. And as the water that evaporates rises right to the sun, and returns here. What we see is the great golden rushing thither, from the death exhalation, towards the sun, as a great cloud of bees flying to swarm upon the invisible queen, circling round, and loosing again. This is what we see of the sun. The center is invisible for ever. And of the moon the same. The moon has her back to us for ever. Not her face, as we like to think. The moon also pulls the water, as the sun does. But not in evaporation. The moon pulls by the magnetic force we call gravitation. Gravitation not being quite such a Newtonian simple apple as we are accustomed to find it, we are perhaps farther off from understanding the tides of the ocean than we were before the fruit of the tree fell to Sir Isaac's head. It is certainly not simple little-things tumble-towards-big-things gravitation. In the moon's pull there is peculiar, quite special force exerted over those water-born substances, phosphorus, salt, and lime. The dynamic energy of salt water is something quite different from that of fresh water. And it is this dynamic energy which the sea gives off, and which connects it with the moon. And the moon is some strange coagulation of substance such as salt, phosphorus, soda. It certainly isn't a snowy cold world, like a world of our own gone cold. Nonsense. It is a globe of dynamic substance like radium or phosphorus, coagulated upon a certain vivid pole of energy, which pole of energy is directly polarized with our earth, in opposition with the sun. The moon is born from the death of individuals. All things, in their oneing, their unification into the pure, universal oneness, evaporate and fly like an imitation breath towards the sun. Even the crumbling rocks breathe themselves off in this rocky death, to the sun of heaven, during the day. But at the same time, during the night they breathe themselves off to the moon. If we come to think of it, light and dark are a question both of the third body, the intervening body, what we will call, by stretching a point, the individual. As we all know, apart from the existence of molecules of individual matter, there is neither light nor dark. A universe utterly without matter, we don't know whether it is light or dark. Even the pure space between the sun and moon, the blue space, we don't know whether, in itself, it is light or dark. We can say it is light, we can say it is dark. But light and dark are terms which apply only to ourselves, the third, the intermediate, the substantial, the individual.
