This journey went on for four circlings round the whole, and then the whole stream or army of Egos from the old Moon Chain had arrived, and being complete, no more entered after the middle of the Fourth Round. The same circling process of these differently arrived classes goes on for seven complete Rounds of the whole seven planetary centres of consciousness, and when the seven are ended as much perfection as is possible in the immense period occupied will have been attained, and then this chain or mass of “globes” will die in its turn to give birth to still another series. Each one of the globes is used by evolutionary law for the development of seven races, and of senses, faculties and powers appropriate to that state of matter: the experience of the whole seven globes being needed to make a perfect development. Hence we have the Rounds and Races. The Round is a circling of the seven centres of planetary consciousness; the Race the racial development on one of those seven. There are seven races for each globe, but the total of forty-nine races only makes up seven great races, the special septennate of races on each globe or planetary centre composing in reality one race of seven constituents or special peculiarities of function and power. And as no complete race could be evolved in a moment on any globe, the slow, orderly processes of nature, which allow no jumps, must proceed by appropriate means. Hence sub-races have to be evolved one after the other before the perfect root race is formed, and then the root race sends off its off-shoots while it is declining and preparing for the advent of the next great race. As illustrating this, it is distinctly taught that on the Americas is to be evolved the new—sixth—race; and here all the races of the earth are now engaged in a great amalgamation from which will result a very highly developed sub-race, after which others will be evolved by similar processes until the new one is completed. Between the end of any great race and the beginning of another there is a period of rest, so far as the globe is concerned, for then the stream of human Egos leaves it for another one of the chain in order to go on with further evolution of powers and faculties there. But when the last, the seventh, race has appeared and fully perfected itself, a great dissolution comes on, similar to that which I briefly described as preceding the birth of the earth’s chain, and then the world disappears as a tangible thing, and so far as the human ear is concerned there is silence. This, it is said, is the root of the belief so general that the world will come to an end, that there will be a judgment-day, or that there have been universal floods or fires.
