The Adornment of the Spiritual Marriage, by Jan van Ruysbroeck, [1916], at sacred-texts.com
Now understand and mark this well. The unity of our spirit has two conditions: it is essential, and it is active. You must know that the spirit, according to its essence, receives the coming of Christ in the nakedness of its nature, without means and without interruption. For the being and the life which we are in God, in our Eternal Image, and which we have within ourselves according to our essence, this is without means and indivisible. And this is why the spirit, in its inmost and highest part, that is in its naked nature, receives without interruption the impress of its Eternal Archetype, and the Divine Brightness; and is an eternal dwelling-place of God in which God dwells as an eternal Presence, and which He visits perpetually, with new comings and with new instreamings of the ever-renewed brightness of His eternal birth. For where He comes, there He is; and where He is, there He comes. And where He has never been, thereto He shall never come; for neither chance nor change are in Him. And everything in which He is, is in Him; for He never goes out of Himself. And this is why the spirit in its essence possesses God in the nakedness of its nature, as God does the spirit: for it lives in God and God in it. And it is able, in its highest part, to receive, without intermediary, the Brightness of God, and all that God can fulfil. And by means of the brightness of its Eternal Archetype, which shines in it essentially and personally, the spirit plunges itself and loses itself, as regards the highest part of its life, 56 in the Divine Being, and there abidingly possesses its eternal blessedness; and it flows forth again, through the eternal birth of the Son, together with all the other creatures, and is set in its created being by the free will of the Holy Trinity. And here it is like unto the image of the most high Trinity in Unity, in which it has been made. And, in its created being, it incessantly receives the impress of its Eternal Archetype, like a flawless mirror, in which the image remains steadfast, and in which the reflection is renewed without interruption by its ever-new reception in new light. This essential union of our spirit with God does not exist in itself, but it dwells in God, and it flows forth from God, and it depends upon God, and it returns to God as to its Eternal Origin. 57 And in this wise it has never been, nor ever shall be, separated from God; for this union is within us by our naked nature, and, were this nature to be separated from God, it would fall into pure nothingness. And this union is above time and space, and is always and incessantly active according to the way of God. But our nature, forasmuch as it is indeed like unto God but in itself is creature. receives the impress of its Eternal Image passively. This is that nobleness which we possess by nature in the essential unity of our spirit, where it is united with God according to nature. This neither makes us holy nor blessed, for all men, whether good or evil, possess it within themselves; but it is certainly the first cause of all holiness and all blessedness. This is the meeting and the union between God and our spirit in the nakedness of our nature.
