When you are showing Earth purchase rocaltrol 0.25mcg mastercard, you are rooted down rocaltrol 0.25 mcg on line, heavy, with a stable base; just like Mother Earth. Certainly, you show Water throughout the movements by your fluid style and lack of resistance. You are precise in your movements, like Metal, and stand upright and tall, like Wood. As we saw in the Qigong exercises, each movement has a relationship to an organ, an organ system, or to general Qi flow in the body. You are moving your body in a way that influences your health through the meridians and channels, as well as your physical health through the gentle flexing and bending of the joints. Acupuncture There are two very different ways of looking at acupuncture: from the tradi- tional Chinese perspective and from the modern international perspective. The dominant function of acupuncture is to regulate the circulation of Qi (vital energy) and blood. In it, acupunc- ture was described as a means of letting out excess Qi or blood by making holes in the body along certain pathways, called Jingluo (meridians). For some of these meridians, it was advised to acupuncture in such a way as to let out the blood but not the Qi; for others, to let out the Qi, but not the blood. Many diseases were thought to enter the body through the skin, and then penetrate inward through muscle, internal organs, and, if not cured in a timely fashion, to the bone marrow. By inserting a needle to the appropriate depth—to correspond with the degree of disease penetration—the disease could be let out. Prior to the time when there were microscopes by which people could envision individual cells, and before autopsies revealed the intricate structures within the body, doctors and scholars projected the internal workings of the body from what they could actually experience, which was the world outside the body.
