The Adornment of the Spiritual Marriage, by Jan van Ruysbroeck, , at sacred-texts.com
From inwardness there springs a sensible love, which fulfills the man's heart and the desirous power of the soul. This yearning love, and this sensible fruition of the heart, none can have save he who is inward of heart.
Sensible love is a yearning and savouring delight which we feel in God as the eternal Good, wherein are all other goods. Sensible love forsakes all creatures as regards pleasure, not as regards need. Inward love feels itself moved from within by the Eternal Love; and this it must ever cherish. Inward love easily foregoes and despises all things that it may obtain that which it loves.
