Meister Eckhart,
Sermons (Meister Eckhart) — The Self-Communication of God
“ The Father and the Son have one Will, and that Will is the Holy Ghost, Who gives Himself to the soul so that the Divine Nature permeates the powers of the soul so that it can only do God-like works. Just as a spring, which perpetually flows and waters the roots of the flowers, so that the flowers bloom and receive their colours from the water of the spring, so the Godhead imparts Itself to the capacities of the soul that it may grow in the likeness of God. The more that the soul receives of the Divine Nature, the more it grows like It, and the closer becomes its union with God. ”
