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 05:00 and 07:00 local solartime the Large Intestine meridian is open.
The Yuan Source point of the Large Intestine meridian is LI-4. The internally-externally coupled meridian is Lung. It's Luo Connecting point LU-7 and is combined with LI-4.
Between 05:00 and 07:00 local solartime the Large Intestine meridian is open.
The Yuan Source point of the Large Intestine meridian is LI-4. The internally-externally coupled meridian is Lung. It's Luo Connecting point LU-7 and is combined with LI-4.
