The Principle of Yin and Yang (阴阳论)

Yin (阴) and Yang (阳)

Yin and Yang are present in the Chinese history as a form of logic. They are both neither materials nor energies. They are both complementary in nature and they are used largely to explain the behaviour/relationships between different components of life. This theory is being widely used and it is slowly integrated into the study of TCM. The Yin and Yang theory are used to explain the complicated relationships of the human body.

The figure on the left shows the typical modern representation of the Yin Yang. Yin and Yang can be used to explain the different side of environmental, human behaviour,

Yin and Yang always opposed each other as seen in the figure on the left. Strong energy can dispel weak energy while weak energy can reduce the effect of strong energy. This process will occur until a state of equilibrium is achieved. If the Yin and Yang equilibrium state of the human body is disturbed, the human health will be affected.
The table above shows the Yin and Yang depiction of different components in our environment and human action. As can seen the Yin and Yang are opposing each other. Yin and Yang are mutually created and they fully complement and depend on each other. Yin and Yang change and grow in a cyclic manner and they balanced each other. Yin and Yang are also able to transform into each other.
