Classic of Difficult Issues: Channels and Collaterals

Difficulty 25

Chapter 25

There are twelve regular channels, but the five viscera and six bowels together number only eleven (each viscus and bowel has one channel). What is the extra channel, then?

Answer: This extra channel is the divergent channel of the Hand Lesser Yin Heart Channel and the Heart Governor (Pericardium). The Heart Governor (Pericardium) and the Triple Burner are exterior-interiorly related; both have a name but no actual physical form. Therefore, it is said that there are twelve channels in total.
