This Eastern symbol can be interpreted as balance. As one of the four four boundless qualities to be cultivated within an individual, according to Buddhism, it is equanimity.
There are so very many ways in which to consider balance, for example, within an individual, the impact of genetics and environment. Other balance-able diads include good and evil, right and wrong, war and peace, slow and fast, small and large, too much and too little, the two sides of a see-saw, and so on.
Of course, more than two things can also be balanced, such as the three points on a plane which determine a triangle, and four points in space which determine a four triangular faced solid, a center of gravity of which can be imagined.
When we want to balance more things, it is more difficult to visualize, and then we can consider that we are in multiple dimensional space.
