When you change the flow of qi in the physical body through practice of qigong, tai chi or bagua, you create a shift from stagnancy towards vibrancy. If the blockages are minor (e.g. daily stress), the shift can be permanent; if, however, the blockages are old and lodged deep in the body, any shift will be temporary (at best) as the energetic pattern of the blockage will pull the body back into the closed or distorted state. If you practise regularly, eventually the balance tips and the shift can become permanent.
Tao journal, February 2013 excerpt:
As one of the three key streams of Tao energy arts, Five Element Theory can be applied to understand the manifest world in which we live, such as feng shui and astrology, music and military strategy, martial arts and medicine, diet and therapy. There are many schools of thought and many dozens of systems available to work with the Five Elements. For example, the Creation-Destruction Cycles—or Wood-Fire-Earth-Metal-Water and Wood-Earth-Water-Fire-Metal, respectively—were popularised during the first half of the Han Dynasty (206 BC-220 AD), and remain widespread today.
However, Old Taoism’s approach to the Five Elements is primarily concerned with transformation in body, mind and chi. The Transformational Cycle is represented as: Water-Fire-Wood-Metal-Earth.
