In part 90 of this 90 part series, Master Sha teaches viewers what is the Tao Song Channel and how to develop it. Viewers learn the importance of this channel for their lives. This channel begins at the base of the torso, at an acupuncture point called the Hui Yin, and goes up to an acupuncture point at the top of the head called the Bai Hui, before it cycles back down to the Hui Yin. These two acupuncture points carry great significance. Master Sha leads viewers to apply the Four Power Techniques to clear blockages in the Tao Song Channel and teaches them a special mantra to chant. All viewers receive Tao treasures of Tao Harmony Crystal Light Soul Mind Body Transplants. Master Sha offers acupuncture to a man who experiences touching results after his session.
