Teacher: An open-eyed man falling down a well.
YES! PREACH IT. You're going to die, it's not going to ever happen to you again; why not at least witness it? Find out what it looks like. Closing your eyes isn't going to help you. etc.
Also:
The only way to be sure of your path is to close your eyes.
How can you say you're sure if your eyes are open? If you were really sure, you'd close your eyes and just walk, right? This one is actually from a Christian Monk, I believe. I don't have the book in front of me (it's in a box somewhere), but I read it at the store today, and they both impressed me enough to make me give a rough paraphrase.
