And what really is, at a Zen sesshin, is often fatigue, boredom, and pain in our legs. What we learn from having to sit quietly with that discomfort is so valuable that if it didn’t exist, it should. When you’re in pain, you can’t spin off. You have to stay with it. There’s no place to go. So pain is really valuable.
Pain allows us to focus on the pain, and how we are big and strong and can endure the pain. It allows us to not focus on what is happening.
It's a crutch.
