(19) And the Light of the Sun is as it were a God in the Nature of this World, and by its Virtue [and Influence] it continually kindles the Stars [or Constellations] whereby the Stars [or Constellations] (which are of a very terrible and anguishing Essence) continually exult in Triumph very joyfully. For it [the Sun] is an Essence like the Light of God, which kindles and enlightens the dark Mind of the Father, from whence, by the Light, there arises the divine Joy in the Father.

(19) For as the Deity is the Virtue [or Power] and Light of Paradise in the second Principle, so the Sun is the Virtue [or Power] and Light of this material World in the third Principle. And as the Deity shines in the Darkness in the first Principle, so the Sun shines in the Darkness in the third Principle. And as the Deity is the eternal Virtue and the Spirit of the eternal Life, so the Sun is the Spirit and the Virtue in the corruptible Life.

(11) None but the sun can display the sun, If you would see it displayed, turn not away from it. Shadows, indeed, may indicate the sun's presence, Shadows induce slumber, like evening talks, But when the sun arises the "moon is split asunder." In the world there is naught so wondrous as the sun, Though the material sun is unique and single, But the Sun of the soul, beyond this firmament, Where is there room in conception for His essence, So that similitudes of HIM should be conceivable?

(10) The sun does not thine there, nor the moon and the stars, nor these lightnings, and much less this fire. When he shines, everything shines after him; by his light all this is lighted.

(33) In the rare treatise The Secret Symbols of The Rosicrucians, Franz Hartmann defines the sun alchemically as: "The symbol of Wisdom. The Centre of Power or Heart of things. The Sun is a centre of energy and a storehouse of power. Each living being contains within itself a centre of life, which may grow to be a Sun. In the heart of the regenerated, the divine power, stimulated by the Light of the Logos, grows into a Sun which illuminates his mind." In a note, the same author amplifies his description by adding: "The terrestrial sun is the image or reflection of the invisible celestial sun; the former is in the realm of Spirit what the latter is in the realm of Matter; but the latter receives its power from the former."
