"The meaning of 'Qi Gong' in Chinese is that Qi can work when it becomes air and bioenergy. Qi Gong means Qi at work. Qi Gong is a natural abdominal breathing technique that mimics the breathing of an infant, involving tightening the muscles of the coccyx each time you take a deep breath. Ancient Taoism defined this technique as the anal breathing method because the founders of Qi Gong could feel air being drawn in through the anus into the spine or the aorta. To practice this technique, you must half-close your eyes, focus on your tailbone, and relax your muscles while exhaling naturally. The function of the tailbone muscles is like a pump; it drives the Qi from the starting point, CV-1, up through the anus to the spine and the aorta. The main source of Qi is the sexual energy center, the ejaculation control valve, or the epicenter."
