“ Centering, however, is easier said than done. This I learned from a ceramics class I once took. The teacher made throwing a pot look easy, but the thing is, it takes lots of precision and skill. You slam the ball of clay down in the absolute center of the pottery wheel, and with steady hands you push your thumb into the middle of it, spreading it wider a fraction of an inch at a time. But every single time I tried to do it, I only got so far before my pot warped out of balance, and every attempt to fix it just made it worse, until the lip shredded, the sides collapsed, and I was left with what the teacher called “a mystery ashtray,” which got hurled back into the clay bucket. So what happens when your universe begins to get off balance, and you don’t have any experience with bringing it back to center? All you can do is fight a losing battle, waiting for those walls to collapse, and your life to become one huge mystery ashtray. ”
