“Imagine trying to hold the tail of a comet as it blazes across the heavens. It’s burning your hands, eating you up, but there’s no malice in it; a comet can’t possibly know or care about you. You will sacrifice all you are or ever will be for that comet because it suffuses every inch of your skin with a sweet itch you cannot catch, and through its grace you discover velocities you never dreamt possible.”
