When I dance, I dance; when I sleep, I sleep. It sounds so simple, put like this, but nothing is harder to do. This is why Zen masters spend a lifetime, or several lifetimes, learning it. Even then, according to traditional stories, they often manage it only after their teacher hits them with a big stick—the keisaku, used to remind meditators to pay full attention. Montaigne managed it after one fairly short lifetime, partly because he spent so much of that lifetime scribbling on paper with a very small stick.
