Yin Yang is a principle of chinese philosophy, where yin and yang are two opposite energies. Yin means darkness being represented by the side painted black, and yang is lightness.
Light, which is luminous energy and presents itself in a very intense way, is yang, and very weak light is yin. According to the Chinese, the world is composed of opposing forces and finding the balance between them is essential.
Some authors describe it as the moon and the sun, the man and the woman, but they are wrong definitions. Chinese philosophy is basically composed of energy, negative and positive. The two spheres within the symbol symbolize the idea that whenever each of the forces reaches its extreme point, an opposite feeling manifests within itself.
In the world of tattoos, the yin yang symbol is one of the most popular as it represents balance.
