“Ki” is the Korean word for cosmic vitality that is the true essence of every creation in the cosmos. Most people begin their understanding of Ki by experiencing it as bio-energy or the vital life force in the body. Ki is the connection between the physical body and conscious mind. When practitioners learn to control the Ki in their bodies, they begin to understand that they have control over their bodies. In the orient, people have known about Ki for thousands of years. Oriental medicine, such as acupuncture or acupressure, utilizes the knowledge of Ki-energy by healing people through correcting the distorted energy flow in their body.
