As all material creation consists of out-births of things spiritual, the spiritual world being the world of causes, and the natural world that of effects, and as effects are the repositories of their causes, the natural world is the reflection of the spiritual. For this reason, from the beginning of things, the sun has stood out as a pre-eminent symbol of the things of God. Of all inanimate things it bears the closest correspondence to the Supreme Being, for what it is in the natural world the Supreme Being is in the Spiritual. Its central fire is the correspondence of the essence of the Divine Nature--DIVINE LOVE; its heat the correspondence of the heat flowing from Divine Love, which is Divine Goodness and all that that comprises; its light the correspondence of Divine Truth which is the light proceeding from Divine Wisdom; and the union of heat and light in its central essence forever symbolizes the union of the Divine Love and Wisdom resulting from that of the Divine Will and Understanding.God is the SUN from whose heat and light--His Love and Wisdom--proceed all that is spiritual, and through the spiritual, by the medium of the natural sun, all that is natural. The sun is supreme in all natural things, and its operations run through all in its own world, but the Divine SUN from which it derives its origin is supreme in all and operates through all, above and below. And as the natural sun is everywhere present in its own realm, and all things derive their life and grow in more or less perfect measure according to their forms and distances, so is the Supreme One omnipresent, filling both the spiritual and the natural world.
