When silence, wonder, adoration are diminished, so are human beings. We imagine we can get by on love and indeed we can. But love shrivels up and dies in the absence of contemplation and adoration. Love, human love, needs to be transfigured, transcended, if it is to be true to its deepest self.
If the eyes are the windows of the soul, then the voice is the window opened up and the sound of the soul coming out.
