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 09:00 and 11:00 local solartime the Spleen meridian is open.
The Yuan Source point of the Spleen meridian is SP-3. The internally-externally coupled meridian is Stomach. It's Luo Connecting point ST-40 and is combined with SP-3.
