And that is truly the beauty of a well-run session. The leader carefully times, announces, forces a pose change and starts the clock again. You are at the mercy of the tick tick ticking and forced to shut out all of your hesitation and just do it. While others are watching. And there, in that space between thoughts, you are awakened.
Every fiber of your being is in the moment, in flow, observing and responding, not thinking, just being. In a packed classroom, "the sea of all beings" is right there, ebbing and flowing around you, touching but not touching as you are completely alone but not alone. Finally, finally - the monkey mind (of which I am ABSOLUTELY CERTAIN I am the QUEEN) is hushed. Oh bliss! Oh perfection! Let's do that again, shall we?
