The mission of the Prophets, the revelation of the Holy Books, the manifestation of the heavenly Teachers and the purpose of divine philosophy all center in the training of the human realities so that they may become clear and pure as mirrors and reflect the light and love of the Sun of Reality. Therefore, I hope that—whether you be in the East or the West—you will strive with heart and soul in order that day by day the world of humanity may become glorified, more spiritual, more sanctified; and that the splendor of the Sun of Reality may be revealed fully in human hearts as in a mirror.
