As mentioned in previous articles, one of the most important theories in Traditional Japanese acupuncture and shiatsu massage is that of the “Five Phases of Transformation”. Part 1 described how these five phases known as Wood, Fire, Earth, Metal, and Water are used to categorize a wide variety of natural phenomena. Part 2 explained the Generating Cycle, the first of several relationships which describe how the various phases inter-relate to each other in Nature.
The second of these inter-relationships is called the Restraining Cycle (sometimes also referred to as the Control Cycle). In a healthy system, the Restraining Cycle helps to maintain order and balance
By observing Nature
- Wood restrains Earth by providing a healthy covering of plant life to prevent soil erosion
- Earth restrains Water by forming embankments to keep the rivers and irrigation ditches from overflowing and flooding
- Water restrains Fire by preventing overheating
- Fire restrains Metal by purifying and refining during metalworking
- Metal restrains Wood by using farming implements and other tools to keep overgrowth in proper check, and the entire cycle repeats
However, when one phase begins to dominate, the system can become unhealthy and out of balance and the Restraining Cycle gives way to Destruction
