Yin and Yang are two opposite and complementary forces that represent the dual nature of all things in the universe, such as night and day, or cold and hot. Yin embodies qualities that are cool, calm, passive, and nurturing, while Yang represents warmth, activity, energy, and dynamism. Though opposites, Yin and Yang are interdependent and constantly influence each other. Good health arises from maintaining a harmonious balance between these forces, ensuring that neither dominates or diminishes the other. This balance is essential for physical, emotional, and spiritual well-being.
