During the meditations, Chunyi came over and put his sword fingers on our third eyes and his palm on our heads. The first time he did that to me, nothing happened. Then, later in the retreat, he did it a second time. I felt a powerful current of energy flow through my upper dantian down through the central energy column to settle at the bottom of the torso. It was warm and immensely powerful. I still have no idea what that did, but it sure did something!
