“Like you're riding a train at night across some vast plain, and youcatch a glimpse of a tiny light in a window of a farmhouse. In aninstant it's sucked back into the darkness behind and vanishes. Butif you close your eyes, that point of light stays with you, justbarely for a few moments.”

“There's always light after the dark. You have to go through that dark place to get to it, but it's there, waiting for you. It's like riding on a train through a dark tunnel. If you get so scared you jump off in the middle of the ride, then you're there, in the tunnel, stuck in the dark. You have to ride the train all the way to the end of the ride.”

“Let's pretend for just one moment that could actually happen. You close your eyes and I'll close mine and let's dream the same dream across the Atlantic, lighting up the darkness between us. Can you see it, Stu? Can you see us up there, shining in all the black?”

“When you're born a light is switched on, a light which shines up through your life. As you get older the light still reaches you, sparkling as it comes up through your memories. And if you're lucky as you travel forward through time, you'll bring the whole of yourself along with you, gathering your skirts and leaving nothing behind, nothing to obscure the light. But if a Bad Thing happens part of you is seared into place, and trapped for ever at that time. The rest of you moves onward, dealing with all the todays and tomorrows, but something, some part of you, is left behind. That part blocks the light, colours the rest of your life, but worse than that, it's alive. Trapped for ever at that moment, and alone in the dark, that part of you is still alive.”

“Don't think about what you've left behind" The alchemist said to the boy as they began to ride across the sands of the desert. "If what one finds is made of pure matter, it will never spoil. And one can always come back. If what you had found was only a moment of light, like the explosion of a star, you would find nothing on your return.”

“An ordinary mirror is silvered at the back but the window of the night train has darkness behind the glass. My face and the faces of other travellers were now mirrored on this darkness in a succession of stillnesses. Consider this, said the darkness: any motion at any speed is a succession of stillnesses; any section through an action will show just such a plane of stillness as this dark window in which your seeking face is mirrored. And in each plane of stillness is the moment of clarity that makes you responsible for what you do.”
