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 15:00 and 17:00 local solartime the Urinary Bladder meridian is open.
The Yuan Source point of the Urinary Bladder meridian is UB-64. The internally-externally coupled meridian is Kidney. It's Luo Connecting point KI-4 and is combined with UB-64.
Between 15:00 and 17:00 local solartime the Urinary Bladder meridian is open.
The Yuan Source point of the Urinary Bladder meridian is UB-64. The internally-externally coupled meridian is Kidney. It's Luo Connecting point KI-4 and is combined with UB-64.
