""The love of God, unutterable and perfect, flows into a pure soul the way light rushes into a transparent object. The more love that 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."
