It'll hurt more than you've ever been burned, and you will have a scar. If meditation worked for cancer, it could work for this. Stay with the pain. Don't shove to center. No, no! Oh, God! Look at your hand. The first soap was made from the ashes of heroes, Like the first monkey shot into space. Without pain, without sacrifice, we would have nothin'. I tried not to think of the the words "sear" or "flesh." Stop it! This is your pain. This is your burning hand. It's right here. I'm going to my cave. I'm going to my cave and find my power animal. No! Don't deal with it the way those dead people do! Come on! I get the point! OK! Please! No. What you're feeling is premature enlightenment.
