In the _Aurora_, the “Root or Mother of Philosophy, Astrology and Theology,” he gives a method of division in which he places these sciences in proximity, and yet appears merely to pass from one to the other without any clear definition or determination. “(1) In Philosophy divine power is treated of, what God is, and how in the Being of God nature, stars and _Elementa_ are constituted; whence all things have their origin, what is the nature of heaven and earth, as also of angels, men and devils, heaven and hell and all that is creaturely, likewise what the two qualities in nature are, and this is dealt with out of a right ground in the knowledge of spirit, by the impulse and motion of God. (2) In astrology the powers of nature, of the stars and elements, are treated of, and how all creatures proceed from them, how evil and good are through them effected in men and animals. (3) In theology the kingdom of Christ is dealt with, as also its nature, and how it is set in opposition to hell, and how in nature it wars with the kingdom of darkness.”[126] 1. What comes first is God the Father; this first is at once divided in itself and the unity of both its parts. “God is all,” he says, “He is the Darkness and the Light, Love and Anger, Fire and Light, but He calls Himself God only as to the light of His love. There is an eternal _Contrarium_ between darkness and light; neither comprehends the other and neither is the other, and yet there is but one essence or substance, though separated by pain; it is likewise so with the will, and yet there is no separable essence. One single principle is divided in this way, that one is in the other as a nothing which yet exists; but it is not manifest in the property of that thing in which it is.”[127] By anguish is expressed that which we know as the absolute negativity—that is the self-conscious, self-experienced, the self-relating negativity which is therefore absolute affirmation. All Boehme’s efforts were directed towards this point; the principle of the Notion is living in him, only he cannot express it in the form of thought. That is to say, all depends on thinking of the negative as simple, since it is at the same time an opposite; thus anguish [Qual] is the inward tearing asunder and yet likewise the simple. From this Boehme derives sources or springs [Quellen], a good play on the words. For pain [die Qual], this negativity, passes into life, activity, and thus he likewise connects it with quality [Qualität], which he makes into Quallity.[128] The absolute identity of difference is all through present to him.
