Na Zi Fa - Yuan points combined with coupled Luo points
To enhance the action of Yuan Source point of the open meridian, it can be combined with the Luo Connecting point of the internally-externally coupled meridian. In this way a transverse connection between Yin and Yang meridian pairs is made. This forms a very effective combination.
Example
Between 07:00 and 09:00 local solartime the Stomach meridian is open.
The Yuan Source point of the Stomach meridian is ST-42. The internally-externally coupled meridian is Spleen. It's Luo Connecting point SP-4 and is combined with ST-42.
