Logician –
I don’t think MiddlePath is saying that he doesn’t ever feel pain. He’s not a stone. And you can’t feel joy if you can’t feel pain. He is saying, if I am understanding correctly, that he reacts in a positive way, even to things which might be painful. He has a perspective on pain, which makes it something which isn’t bad even though it hurts. That is an amazing thing that we should all strive for.
