"If these tiles were on the ground in the old town square, any fool could walk them," said Benedetta. "No one would ever slip or fall. The tiles are not dangerous. The danger is inside you. In your head, in your heart. It’s your self that is the danger. If you can possess your self, then you go sign your name on the post and you walk back to us. It is safe as a pillow, safe as a bed; no, darling, it’s safer than that, because there are men in the world. But to walk beneath the stars—well, it’s in you, or it isn’t in you."
