The Adornment of the Spiritual Marriage, by Jan van Ruysbroeck, , at sacred-texts.com
Now understand this: this man shall go out and observe God in His glory with all saints. And he shall behold the rich and generous outflowing of God, with glory, and with Himself, and with inconceivable delights towards all the saints, according to the longing of all spirits; and how these flow back, with themselves, and with all that they have received and can achieve, towards that same rich Oneness from which all bliss comes forth.
This flowing forth of God always demands a flowing back; for God is a Sea that ebbs and flows, pouring without ceasing into all His beloved according to the need and the merits of each, and ebbing back again with all those who have been thus endowed both in heaven and on earth, with all that they have and all that they can. And of some He demands more than they are able to bring, for He shows Himself so rich and so generous and so boundlessly good: and in showing Himself thus He demands love and adoration according to His worth. For God wishes to be loved by us according to the measure of His nobility, and in this all spirits fail; and therefore their love becomes wayless and without manner, for they know not how they may fulfil it, nor how they may come to it. For the love of all spirits is measured: and for this reason their love perpetually begins anew, so that God may be loved according to His demand and to the spirit's own desires. And this is why all blessed spirits perpetually gather themselves together and form a burning flame of love, that they may fulfil this work, and that God may be loved according to His nobility. Reason shows clearly that to creatures this is impossible; but love always wills the fulfilment of love, or else will be consumed, burned up, annihilated in its own failure. Yet God is never loved according to His worth by any creatures. And to the enlightened reason this is a great delight and satisfaction: that its God and its Beloved is so high and so rich that He transcends all created powers, and can be loved according to His merits by none save Himself.
This rich and enlightened man shall distribute gifts to all the angelic choirs, and all spirits, each in particular according to its merits, out of the richness of his God and out of the generosity of his own ground; which is illuminated and overflowing with great and wonderful gifts. He passes through all choirs, through all hierarchies and orders, and beholds how God dwells in all according to the merit of each. This enlightened man goes swiftly and in ghostly wise round and through all the heavenly hosts, rich and overflowing with charity, and enriching and inundating the whole celestial company with fresh glory out of the Richness and Abundance of the Trinity and Unity of the Divine Nature.
This is the first going out, towards God and towards all saints.
