In life, you find yourself in a dark room from which you cannot see any way out. You are groping blindly along the walls, which are featureless and smooth. Finally, after what seems an eternity, you find in the dark a doorknob. When you turn it, a door opens, and you pass into another chamber, only to find that it, too, is perfectly dark and featureless. When you finally find another door, it opens into another dark chamber. And so it repeats, a blind stumbling, until one day, after a lifetime of searching, you open a door into a new place, one that is not dark, but perfectly, radiantly light. That last door is death.
