There is a special light people shine under when you are first getting to know them. I wonder if that is the only time that light is shone. Can the light come back? Or can one work for it to never go out?
Then of course there is a light that never goes out. One which involves a different mechanism. more like a chiaroscuro of the soul. An exercise in forever.
A night light or a slippery street light; insighters of shadows and lonely dancers.
First morning light and deep orange evenings. Through windows or leaves or incense filled rooms.
A faint candle light that hides the imperfections of reality and leaves you with magic.
