Nothing wakes you up out of your habits and patterns of body mind and breath like class with Prashant Iyengar. Last night's class was no exception. He said (I'm paraphrasing) "The Iyengar students are always fixing, adjusting, repairing...it is like I have sold you a car which is always in the shop. You are always taking it to the garage for repair! You are always doing, doing, doing and it is never done. When is your vehicle going to run?"He went on to describe drinking a cup of tea when you are on an Indian train -- the skill it takes to sip your tea without spilling it! He said it was like we were always pulling the emergency brake in order to stop and sip our tea. Being like the conductor, he said we should not be surprised if we sensed a bit of irritation or admonishment in his tone because we keep interrupting his flow by pulling the chain! He led us through Sirsasana cycle (as opposed to variations) a term he used specifically for it's implication of continuity. He asked us not to "jerk and jolt" while we went through the cycle, not to create tremors in the body, mind or breath. We kept that up through the standing poses, Sarvangasana and then some forward extensions. I kept my vehicle running all the way home to dinner.
