I learned about Jewish spirituality in a yoga class in 1971. I lay prone on the carpeted floor, relaxing after achieving the challenging bridge posture for the first time. I had thought that the pose’s name came from its shape: Lying on my back, I pushed my feet and hands into the floor until the trunk of my body rose in an arc that resembled a bridge. But as I regained equilibrium after the posture, I became uncertain about the name. As I lay there, I had the sense that the pose had enabled me to bridge the breach between the living and the dead, the holy and the profane, the body and the soul. Everything felt profoundly connected. I began to weep, and from my unconscious rose the words of the Shema. I chanted and lingered on the word echad (one). I lay there, my cells tingling, sensing the holy connection between all things. Like Job, I knew God in my flesh.
