In addition to the 12 regular meridians, Qi also flows within the 8 Extraordinary Vessels. These Vessels are said to act as "reservoirs" for Qi. Using the 8 Extraordinary Vessels opens up a whole new level of possibility for your hands-on practice.
Since the Extraordinary Vessels do not have points of their own (except for the Du and the Ren), knowing how to use Master Points is the key to accessing the deeper potential of these Vessels.
The Master Points are located on the 12 regular meridians and are used to activate the Extraordinary Vessels. You will learn when to use each Master Point, how to combine them to obtain the best results, and how to precisely locate each point.
