Here we have humanity constituted and the races launched in their career through the cataclysms of the globe. But on this globe which, at birth, we take as being the immutable base of the world and which itself is carried along floating in space, on these continents which emerge from the seas to disappear afresh, amid these passing peoples, these crumbling civilizations, what is the mighty and poignant, the eternal mystery? This is the great inner problem, that of each and all, the problem of the soul which discovers in itself an abyss of darkness and light, regarding itself with a mixture of delight and terror and saying to itself: “I am not of this world, for it is not sufficient to explain me. I do not come from earth and I am going elsewhere. Where?” That is the mystery of Psyche, the mystery containing all the rest. The cosmogony of the visible world, said Pythagoras, has led us to the history of the earth, and the latter to the mystery of the human soul. With it we touch the sanctuary of sanctuaries, the holy of holies. Once its consciousness aroused, the soul becomes for itself the most astonishing of sights. But even this consciousness is only the enlightened surface of its being, in which it suspects there to be dark and unfathomable abysses. In its unknown depths, the divine Psyche contemplates with fascinated look all lives and worlds, past and present, and the future joined to them by Eternity. “Know thyself, and thou shalt know the universe of the gods.” Such was the secret of the sages and initiates. To penetrate through this narrow door into the immensity of the invisible universe, let us awake in ourselves direct vision of the purified soul, and arm ourselves with the torch of intelligence, with the science of the sacred principles and numbers.
