The Adornment of the Spiritual Marriage, by Jan van Ruysbroeck, , at sacred-texts.com
From this gladness and the fulness of grace and the faithfulness of God, there is born and flows forth the third rill in this same unity of the spirit. This rill, like a fire, enkindles the will, and swallows up and consumes everything into unity. And it fills to the brim and flows through all the powers of the soul, with rich gifts and with a singular nobility: and it calls forth in the will a tender spiritual love without effort.
Now Christ says inwardly within the spirit by means of this burning brook: Go ye out by practices in conformity with these gifts and with this coming. By the first rill, which is a simple light, the memory has been lifted above sensible images, and has been grounded and established in the unity of the spirit. By the second rill, which is an inflowing light, understanding and reason have been enlightened, to know the diverse ways of virtue and of practice, and discern the mysteries of the Scriptures. By the third rill, which is an inpouring heat, the supreme will has been enkindled in tranquil love, and has been endowed with great riches. Thus has this man become spiritually enlightened; for the grace of God dwells like a fountainhead in the unity of his spirit; and its rills cause in the powers an outflowing with all the virtues. And the fountainhead of grace ever demands a flowing-back into the same source from whence the flood proceeds.
