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 11:00 and 13:00 local solartime the Heart meridian is open.
The Yuan Source point of the Heart meridian is HT-7. The internally-externally coupled meridian is Small Intestine. It's Luo Connecting point SI-6 and is combined with HT-7.
Between 11:00 and 13:00 local solartime the Heart meridian is open.
The Yuan Source point of the Heart meridian is HT-7. The internally-externally coupled meridian is Small Intestine. It's Luo Connecting point SI-6 and is combined with HT-7.
