The yin-yang symbol embodies the concept of duality, representing the interdependence of opposites within the universe. This idea suggests that elements such as light and dark, male and female, or order and chaos are not just separate but are complementary forces that create harmony. The symbol emphasizes that within each aspect lies the seed of its opposite, promoting balance and the continuous interplay between contrasting forces. This duality is essential in various philosophical traditions, demonstrating how opposites coexist and work together.
