God speaks to each of us as he makes us,
then walks with us silently out of the night.
These are the words we dimly hear:
You, sent out beyond your recall,
Go to the limits of your longing.
Embody me.
Flare up like flame
And make big shadows I can move in.
What do we call visible light? We call it color. But the electromagnetic spectrum runs to zero in one direction and infinity in the other, so really, children, mathematically, all of light is invisible.
