Focus on these words, and whatever you do don't let your eyes wander past the perimeter of this page. Now imagine just beyond your peripheral vision, maybe behind you, maybe to the side of you, maybe even in front of you, but right where you can't see it, something is quietly closing in on you, so quiet in fact that you can only hear it as silence. Find those pockets without sound. That's where it is. Right at this moment. But don't look. Keep your eyes here.
