Light of the world

"Light always points to something else; it never turns in on itself. It is a medium, a channel for the focus to be on whatever it illuminates. At a performance, the spotlight focuses on the artist. In a surgical theater, the blast of brightness is focused on the field of invasion. In a dark corner, the searching beam of the torchlight shows up what has been lost."
