Set over against this Sun-body would have been a Moon-body, in which other beings of like nature with the Sun-beings would have undergone their experiences in the conditions of heat, air, and water. The progress from the Sun-incarnation to that of the Moon would have consisted in the Sun-beings seeing their own life, as in a reflection of the events on the Moon. They would have thus been able to enjoy it, something which they were still incapable of doing during the Sun incarnation. But evolution did not remain at this stage. Something occurred which was of the deepest significance for all future evolution. Certain beings adapted to the Moon-body, take possession of the element of will (the heritage of the Thrones) which was at their disposal, and by its means develop a life of their own, which takes shape independently of the Sun-life. Alongside of those Moon experiences which are entirely under the influence of the Sun, there arise independent Moon experiences, and, at the same time, states of rebellion or mutiny against the Sun-beings. And the various kingdoms which had arisen on the Sun and Moon, first and foremost of which was the kingdom of man’s ancestors, are drawn into these conditions. In this way the Moon-body contains within it, spiritually and materially, two kinds of life: one that is in inner union with the Sun-life, and another which has “fallen away” from it and goes its own way independently. This division into a twofold life appears in all subsequent events of the Moon incarnation. What presents itself to clairvoyant consciousness in this period of evolution may be realized from the following pictures. The whole basic mass of the Moon is formed of a semi-animated substance which at one time moves sluggishly, at another quickly. This is not yet a mineral mass like the rocks and constituents of the earth upon which present day humanity walks. We might call it a kingdom of plant-minerals, only we have to imagine that the main body of the Moon consists wholly of this plant-mineral substance, as the earth today consists of rock, soil and other substances. Just as now we have towering masses of rock, so there were then harder portions embedded in the Moon’s bulk; these may be compared with hard wooden structures or formations of horn; and as plants now arise out of mineral soil, so the surface of the Moon was covered and penetrated by the second kingdom, consisting of a kind of plant-animal. Their substance was softer than the general mass of the Moon, and more mobile. This kingdom extended over the other, like a viscous sea.
