(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.

(57) Now you may well perceive that the Birth of the Sun takes its Original in the Fire, and attains his Personality and Name in the Kindling of the soft, white, and clear Light, which is Himself; and Himself makes the pleasant Smell, Taste, and Satisfaction [or Reconciliation and Well-pleasing] in the Father, and is rightly the Father's Heart, and another Person; for he opens and produces the second Principle in the Father; and his own Essence is the Power or Virtue and the Light; and therefore his is rightly called the Power or Virtue of the Father.

(22) Now the Sun and the Stars [or Constellations] continually kindle the Tincture, for it is fiery; and the Tincture kindles the Body, with the Matrix of the Water, so that they are always boiling, [rising] and seething. The Stars [or Constellations] and the Sun are the Fire of the Tincture, and the Tincture is the Fire of the Body, and so all are seething. And therefore when the Sun is underneath, so that its Beams [or Shining] is no more [upon a Thing,] then the Tincture is weaker, for it has no Kindling from the Virtue of the Sun. And although the Virtue of the Stars and the quality are kindled from the Sun, yet all is too little, and so it becomes feeble, [or as it were dead.] And when the Tincture is feeble, then the Virtue in the Blood (which is the Tincture) is wholly weak, and sinks into a sweet Rest, as it were dead or overcome.

(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."

(22) The Sun is the Goddess in the third Principle; in the created World (understand, in the material Virtue) it went forth out of the Darkness in the Anguish of the Will, in the Way and Manner of the eternal Birth. For when God set the Fiat in the Darkness, then the Darkness received the Will of God, and was impregnated P for the Birth. The Will causes the [sour] Harshness, the Harshness causes the Attracting, and the Stirring of the Attracting to Mobility causes the Bitterness, which is the Woe, and the Woe causes the Anguish, and the Anguish causes the Moving, Breaking, and Rising up. Now the sour Harshness cannot endure the Stirring, and therefore attracts the harder to itself; and the Bitterness or the Attracting will not endure to be stayed, but breaks and stings so very hard in the Attracting, that it stirs up the Heat, wherein the Flash springs up, and the dark [Sourness or] Harshness is affrighted by the Flash, and in the Shriek the Fire kindles, and in the Fire the Light. Now there would be no Light if the Shriek in the Hardness had not been, but there would have remained nothing but Fire; yet the Shriek in the Harshness of the Fire kills the hard Harshness, so that it sinks down as it were to the Ground, and becomes as it were dead and soft; and when the Flash perceives itself in the Harshness, then it is affrighted much more, because it finds the Mother so very mild, and half dead in Weakness; and so in this Shriek its fiery Property becomes white, soft, and mild, and it is the Kindling of the Light, wherein the Fire is changed into a white Clarity, [Glance, Luster, or Brightness.]

(12) For the Spring of the great Anguish, which was in the Beginning before the Light, in the [tart] Harshness, from which the bitter Sting or Prickle is generated, that is now in the sweet Fountain of the Love in the Light changed from the Water- Spirit, and from Bitterness or Stinging is now become the Fountain or Spring of the Joy in the Light. Thus now henceforth the Fire-flash is the Father of the Light, and the Light shines in him, and is now the only Cause of the moving Birth, and of the Birth of the Love. That which in the Beginning was the raking Source, is now S U L, or the Oil of the lovely pleasant Fountain, which presses through all the Fountains, so that from hence the Light is kindled.

(133) The Sun is a Fire, the Channel of Fire, and the dispenser of Fire.

(20) The [sour, strong, or] bitter Gall, (viz. the terrible poisonous Flash of Fire) kindles the Warmth in the Heart, or the Fire, and is itself the Cause, from whence all else take their Original.

(8) Our Life in the Mother's Body has its Beginning wholly, as is above mentioned, and stands there now in the Quality of the Sun and Stars, where then, with the Kindling of the Light, a Center springs up again, where instantly the noble Tincture thus generates itself (out of the Light, out of the joyful Essences of the [sour] harsh, bitter, and fiery Kind [or Quality,]) and sets the Spirit of the Soul in a great pleasant Habitation: And the three i Essences (viz. Harshness, Bitterness, and Fire) are in the Kindling of the Life so very fast bound one to another, that they cannot (in Eternity) be separated one from another, and the Tincture is their eternal House, wherein they dwell, which [House] they themselves generate from the Beginning unto Eternity, which again gives them Life, Joy, and Lust [or Delight.] The strong Gate of the indissoluble Band of the Soul.
