Durante degli Alighieri ( simply called Dante c. 1265–1321)

 “The love of God, unutterable and perfect, flows into the soul the way that light rushes into a transparent object. The more love it finds, the more it gives itself; so that, as we grow clear and open, the more complete the joy of heaven is. And the more souls who resonate together, the greater the intensity of their love, and, mirror like, each soul reflects the other.”
