"음양" (Yin-Yang) is a fundamental concept in Chinese philosophy that describes the dual nature of reality. It represents the idea that opposite forces are interconnected and interdependent in the natural world. Yin is associated with qualities such as darkness, femininity, and passivity, while Yang represents light, masculinity, and activity. Together, they create balance and harmony. The concept of 음양 is often illustrated through the Yin-Yang symbol, which features a circle divided into black and white sections, each containing a dot of the opposite color. This symbol emphasizes that within each force lies the seed of its opposite, highlighting the dynamic interplay between them in various aspects of life, including health, relationships, and nature.
