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 03:00 and 05:00 local solartime the Lung meridian is open.
The Yuan Source point of the Lung meridian is LU-9. The internally-externally coupled meridian is Large Intestine. It's Luo Connecting point LI-6 and is combined with LU-9.
Between 03:00 and 05:00 local solartime the Lung meridian is open.
The Yuan Source point of the Lung meridian is LU-9. The internally-externally coupled meridian is Large Intestine. It's Luo Connecting point LI-6 and is combined with LU-9.
