Ha, hu, SHH, blow, 呬, xi. Every day, when the six Yang energies have reached their peak, face east and sit quietly. There is no need to close the window or let the wind in. Clench your teeth thirty-six times, stir your tongue in your mouth. When the water is full, rinse your mouth several times. Swallow it in three mouthfuls 啯啯 and send it to your dantian with your mind. Slightly pinch your mouth and say the word "he" to exhale the impurities in your heart. When reciting, no sound should be made; otherwise, it will harm the heart energy. That is, close your mouth and nose to inhale clear air to nourish the heart. When inhaling, no sound should be heard either. But exhale for a short time and inhale for a long time. Repeat this six times and then recite the word "exhale" six times to treat the spleen. Repeat the word 呬 six times to treat the lungs; Recite the character "xu" six more times to treat the kidneys. And as in the previous method, they are called the thirty-six minor celestial spheres. The poem goes: In spring, the wood nourishes the eyes and supports the liver; in summer, the heart fire closes itself; in autumn, the 呬 surely gathers the metal energy and moistens it; in winter, the wind only needs to lack the middle peace. The three Jiao Xi dispels restlessness, and throughout the four seasons, the spleen is constantly exhaled to transform food. It is strictly forbidden to make sounds or smell the mouth and ears. Its effect is even better than that of the Shen Bao Pill.
