To the wise ones of the world who are lovers of the truth it is clear and evident that the purpose of the appearance of the holy and divine Manifestations, the revelation of Books, and the establishment of the religion of God is to foster fellowship and love amongst the members of the human race. Religion is the foundation of spiritual unity, the unity of thought, the unity of perception, the unity of custom. It is the spiritual tie that bindeth all people together so that minds and souls, through divine education, may grow and develop, seek out the truth, and attain unto the highest degrees of human perfection, and that divine civilization may thereby be established. For in the world of being there are two kinds of civilization. One is material civilization, which serveth the world of bodies, and the other is divine civilization, which serveth the world of morality. The founders of material civilization are the wise ones of the world, while the founders of divine civilization are the holy Manifestations of God. Religion is the foundation of divine civilization. Material civilization is like the body, and divine civilization is like the spirit. The body, without spirit, is dead, even should it possess the utmost grace and beauty.
