It is under cyclic law, during a dark period in the history of mind, that the true philosophy disappears for a time, but the same law causes it to reappear as surely as the sun rises and the human mind is present to see it. But some works can only be performed by the Master, while other works require the assistance of the companions. It is the Master’s work to preserve the true philosophy, but the help of the companions is needed to rediscover and promulgate it. Once more the elder brothers have indicated where the truth—Theosophy—could be found, and the companions all over the world are engaged in bringing it forth for wider currency and propagation. The Elder Brothers of Humanity are men who were perfected in former periods of evolution. These periods of manifestation are unknown to modern evolutionists so far as their number are concerned, though long ago understood by not only the older Hindus, but also by those great minds and men who instituted and carried on the first pure and undebased form of the Mysteries of Greece. The periods, when out of the Great Unknown there come forth the visible universes, are eternal in their coming and going, alternating with equal periods of silence and rest again in the Unknown. The object of these mighty waves is the production of perfect man, the evolution of soul, and they always witness the increase of the number of Elder Brothers; the life of the least of men pictures them in day and night, waking and sleeping, birth and death, “for these two, light and dark, day and night, are the world’s eternal ways.”
