Na Zi Fa - Combining Inner Branch Energy points with Yuan Source points
Combining the Inner Branch Energy point with the Yuan Source point on the same open meridian forms a very powerful 'powerpoint' combination. These points together combine the power of inner branch energy and original Qi.
Example
Between 07:00 and 09:00 local solartime the Stomach meridian is open. The Inner Branch Energy of the Stomach meridian is Earth. The Earth point of the Stomach meridian is ST-36. ST-36 is combined with ST-42, the Yuan Source point of the Stomach meridian.
