There was one complicated pose (I think it was Astavakrasana, 8 angle pose) that I struggled with in my back corner of the room. Shiva Rea was in the front, cueing and explaining and encouraging the group. Eventually, I made a slightly different move in my attempt to get it and I heard her exclaim, "Yes!" I looked up from my contortions and she was looking right at me across the room with a gigantic smile. She had been assisting me with her cues all along.
