"Today, to this melody of the Company on high, the world will leap and dance: ‘Glory be to my Lord, the All-Glorious!’ But know ye this: save for this song of God, no song will stir the world, and save for this nightingale-cry of truth from the Garden of God, no melody will lure away the heart. ‘Whence cometh this Singer Who speaketh the Beloved’s name?’"
