Without the Light, the journey of life is fraught with dangers and no traveler's vision can penetrate the haze of self-centeredness. The ímage of God as Light that suffuses all the universe is one that unítes the divine transcendence and immanence... All of creation is replete with "signs" of God's presence, but they cannot be discerned without the Light.
I once heard the pianist, Arthur Rubinstein, being interviewed. At one point he was asked to share his experience of playing Chopin's Nocturnes. He said in effect, "I do not know what it is. But over and over again I have had the experience of sitting in a crowded concert hall playing the Nocturnes and I can feel everyone in the room waiting for the next note." In this moment of waiting, all present find their contemplative community in their oneness with one another in the boundless mystery that enraptures them.
