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 17:00 and 19:00 local solartime the Kidney meridian is open.
The Yuan Source point of the Kidney meridian is KI-3. The internally-externally coupled meridian is Urinary Bladder. It's Luo Connecting point UB-58 and is combined with KI-3.
Between 17:00 and 19:00 local solartime the Kidney meridian is open.
The Yuan Source point of the Kidney meridian is KI-3. The internally-externally coupled meridian is Urinary Bladder. It's Luo Connecting point UB-58 and is combined with KI-3.
