In the second level, we begin to open the Central channel (Zhong-Mai), which connects the crown and perineum in our body (Baihui and Huiyin points), and passes through all three dantians. At the second stage, we work out one part of the Central channel: between the lower and middle Dantians.
Moving the ball and establishing a connection between two Dantians is called ” raising water to the fire and immersing the fire into the water” by Chinese. As the result, swelling and fatigue in legs disappear, kidneys begin to work better, and heart function also improves.
Another aim of opening the Central channel is to increase the energy entering the brain area. As a result, the brain begins to work faster, the strength of one’s physical body increases, the person becomes more active, more mobile.
