The exervcise is good for settling the shen as the two points in the palm of your hands are Laogong, which are the Jing Well points on the Pericardium channel. These points can be activated manually or energetically usually to expel heat or overactivity from the heart so as to steady and rest the shen. They also have a strengthening effect upon the heart so as to harmonise and solidify then Shen.
