"It is like looking for lost drops of rain in a river."
"You're wrong. The mind is not like raindrops. It does not fall from the skies, it does not lose itself among other things. If you believe in me at all, then believe this: I promise you I will find it. Everything depends on this."
"I believe you," she whispers after a moment. "Please find my mind."
