The yin and yang symbol has a long and complicated meaning behind it. In simple terms, it represents the idea that two opposite characteristics can exist in harmony and complement each other. There cannot be positive energy without negative energy.  There cannot be light without darkness. This concept of yin and yang has existed for thousands of years in China.
