Yin and yang is a Chinese philosophical concept that describes opposite but interconnected forces. In Chinese cosmology, the universe creates itself out of a primary chaos of material energy, organized into the cycles of yin and yang and formed into objects and lives. The essence of everything in the Universe is energy, and everything that exists has its own vibration, a frequency range. Nothing is stable, everything is in motion. Our bodies, water, air, plants, soil, especially our thoughts, emotions, words also have a vibration, and we seem to be living on an ocean that is constantly in motion.
