"Hell is a state of mind--ye never said a truer word. And every state of mind, left to itself, every shutting up of the creature within the dungeon of its own mind--is, in the end, Hell. But Heaven is not a state of mind. Heaven is reality itself."
This reminds me of a night (several years ago) when nightmares and foreboding plagued me. I always sleep with earplugs in. It was as if I was floating wretchedly in endless space.
At dawn, I pulled out my earplugs, and what I heard was the most lovely, simple, real thing. It brought me back to earth, back from the whirling torments of a restless mind. A raindrop, landing on my wet windowsill, sounded its single perfect note.
