“I don't believe in anything, Mother," I said. "You told Armand long ago that you believe you'll find answers in the great jungles and forests; that the stars will finally reveal a vast truth. But I don't believe in anything. And that makes me stronger than you think”

“Don't you think it's rather nice to think that we're in a book that God's writing? If I were writing a book, I might make mistakes.
