This exercise is my favorite for some reason

. I still get confused at it sometimes though, partly because I have to imagine the column
inside the torso, while my hands are moving
outside, so it becomes hard to move it. Also I still can't imagine both hands together moving the energy, I jump back and forth between the hand going up (moving the energy up) and the hand going down. Hopefully with time I will be able to accomplish that (^_^).
