Five Phases Of The Universe – Wu Xing

Also known as the Five Elements or Five Movements, the Five Phases represent the actual activities of Yin and Yang energy as manifested in the cyclical changes of nature. They describe various stages of the continual cycle of energy transformation, rising and falling. The Five Phases take their names from the five elements in nature that most closely resemble their functions and characters: wood, fire, earth, metal, and water. Every element represents a different amount of Yin or Yang energy, a different season, a different color, a different organ, a different orientation, etc. They nurture and counteract one another to ensure a harmonious cycle of transformation as nature runs its course.

The relationship of nurture and counteraction is essential. Without nurture, there is no growth; without counteraction, things can overgrow and break the balance. 

Our organs and emotions have characteristics related to the Five Phases; the following table highlights these relationships. In Chinese medicine, the organs are classified as either Zang or Fu. Zangs are somewhat solid organs (e.g., liver, kidney). They have more Yin energy. Fus are the organs with cavities (except the gallbladder), such as the stomach. They have more Yang energy.
