yin-yang symbol

You might have seen this symbol before,whether it's as a temporary tattoo or at a Chinese temple.It's called the yin-yang symbol.It comes from Taoism,a religion born in China and it has far more meaning than you probably realize.The yin is the dark swirl,and the yang is the light one,and each side has a dot of the opposite color,which gives a clue to the meaning of yin and yang.Everything contains the seed of its opposite.
