The Five Elements wood, fire, earth, metal and water are the building blocks with which the human body and, indeed, all matter is composed. Chi is energy, the essence of all life. This vital force maintains and nurtures our bodies, minds and spirits. It is the source of life, inspiration and action. As long as each of these three areas are balanced and in harmony, there is health.
Any imbalance leads to illness.
The purpose of acupressure is to restore and maintain that balance. Think of the Earth, which seeks and maintains an energy balance in its own dramatic way. When energy builds up on the planet Earth to an unhealthy level, the Earth moves the excess energy to a place where the energy level is lower. Wind is caused by local temperature differences seeking balance. Rain is the result of excessive moisture in the atmosphere.
