It must be remembered, however, that these Chosen Ones are not the only ones saved from the destruction that overtakes the majority of the race. On the contrary a few survivors are preserved, although driven away from their former homes, and reduced to "first principles of living" in order to become the parents of the new races. The new races springing from the fittest of these survivors quickly form sub-races, being composed of the better adapted souls seeking reincarnation, while the less fit sink into barbarism, and show evidences of decay, although a remnant drags on for thousands of years, being composed of the souls of those who have not advanced sufficiently to take a part in the life of the new races. These "left-overs" are in evidence in our own times in the cases of the Australian savages, and some of the African tribes, as well as among the Digger Indians and others of similar grade of intelligence. In order to understand the advance of each race it must be remembered that the more advanced souls, after passing out of the body, have a much longer period of rest in the higher planes, and consequently do not present themselves for reincarnation until a period quite late when compared with the hasty reincarnation of the less advanced souls who are hurried back to rebirth by reason of the strong earthly attachments and desires. In this way it happens that the earlier races of each Cycle are more primitive folk than those who follow them as the years roll by. The soul of an earth-bound person reincarnates in a few years, and sometimes in a few days, while the soul of an advanced man may repose and rest on the higher planes for centuries--nay, even for thousands of years, until the earth has reached a stage in which the appropriate environment may be afforded it. Observers, unconnected with Occultism, have noted certain laws which seem to regulate the rise and fall of nations--the procession of ruling races. They do not understand the law of Metempsychosis that alone gives the key to the problem, but nevertheless they have not failed to record the existence of the laws themselves. In order to show that these laws are recognized by persons who are not at all influenced by the Occult Teachings, we take the liberty of quoting from Draper's "History of the Intellectual Development of Europe."
