The principle behind yin and yang is TAO. TAO is a fundamental concept in Chinese philosophy that represents the natural order and harmony that underlies all things in the universe. The concept of yin and yang is a part of this philosophy, and it describes the complementary and interconnected nature of opposing forces. Yin and yang are two opposing, yet complementary aspects of the natural world. Yin represents darkness, feminine, passive, and cold, while yang represents light, masculine, active, and warm. The TAO teaches that the balance between yin and yang is necessary for harmony and order in the world, and understanding this principle is essential for achieving balance in one’s life.
