ed that there is an intimate relationship between the activity and life of human beings and their natural environment. The root of all life is yin and yang; this includes everything in the universe, with heaven above and earth below, within the four directions and the nine continents. In the human body there are the nine orifices of ears, eyes, nostrils, mouth, anus, and urethra; the five zang organs of kidney, liver, heart, spleen, and lungs; and the twelve joints of elbows, wrists, knees, ankles, shoulders, and hips, which are all connected with the five earthly transformative energies, also known as the five elemental phases that consist of wood, fire, earth, metal, and water”

• “the yang qi of the body is like the sun. if the sun loses its brilliance or illuminating effect, all things on earth become inactive. The sun is the ultimate yang. This heavenly energy of the sun, yang qi circulates around the center or core and has the function of protecting the body.”

• 故阳气者，一日而主外。平旦人气生，日中而阳气隆，日西而阳气已虚，气门乃闭。

• The yang qi moves like the sun. as the sun begins to rise at dawn, the yang qi begins to move to the outer body, and the pores open. The peak of the yang qi is at noon, and when the yang qi is most active it is advisable to relax and stay quiet so that the yang qi does not escape.

21

• 是故暮而收拒，无扰筋骨，无见雾露，反此三时，形乃困薄。

• As the sun sets, the yang qi moves inward and the pores begin to close. At this time it is harmful to engage in strenuous physical activity or expose oneself to cold, damp , mist, or fog. If one violates the natural order of the yang qi as it rises, peaks, and sets, the body will gradually be weakened by pathogenic factors and be subject to disease and degeneration.

organs and the fountain of the qi .yang protects the exterior of the body against pathogens and makes the muscles function.

• 阴不胜其阳，则脉流薄疾，并乃狂。阳不胜其阴，则五脏气争，九窍不通。

• When the yin fails to contain the yang ,the flow in the channels will become rapid, causing the yang qi to become excessive and reckless. If the yang qi is deficient and unable to counterbalance the yin, communication between the internal organs will be disrupted, and the nine orifices will cease to dysfunction .
