Shiatsu massage, sometimes called Zen shiatsu, unifies spiritual, philosophical, and medical aspects of the body. Some westernized massage techniques are combined with the view that energy, qi or chi, circulates along channels called meridians. Shiatsu is efective because it deals with the body as a whole component. The shiatsu therapists believe that everything in the body is connected and each organ influences other organs. When the human body is healthy and the systems as a whole works correctly this means that there is a great harmony of energies flowing inside the body through the meridians.
