Traditionally, which pair is used to represent Yin/Yang?

In traditional Chinese philosophy, the concepts of Yin and Yang represent complementary forces that are interdependent and exist in relation to one another. The pair Earth and Heaven serves as a profound representation of this duality.

Earth embodies qualities associated with Yin, such as receptivity, nurturing, and groundedness, whereas Heaven symbolizes qualities related to Yang, such as activity, brightness, and expansiveness. This pairing highlights the balance and interactions between the two realms and their influence on the natural world and human life.

Furthermore, this relationship between Earth and Heaven is foundational in Taoist cosmology and reflects how these opposing forces shape existence. The synergy between Earth and Heaven underscores the essential balance of Yin and Yang in understanding the universe's dynamics and the patterns of life.

The other options do not encapsulate the profound duality and relationship that Earth and Heaven convey in the context of Yin and Yang.
