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 21:00 and 23:00 local solartime the Triple Burner meridian is open.
The Yuan Source point of the Triple Burner meridian is TB-4. The internally-externally coupled meridian is Pericardium. It's Luo Connecting point PC-6 and is combined with TB-4.
Between 21:00 and 23:00 local solartime the Triple Burner meridian is open.
The Yuan Source point of the Triple Burner meridian is TB-4. The internally-externally coupled meridian is Pericardium. It's Luo Connecting point PC-6 and is combined with TB-4.
