There are many balancing forces in the world. Light and dark, up and down, hot and cold to name a few. At first they may appear to be opposing elements, but they’re actually complementary and connected. Without two sides of the same coin, the coin couldn’t exist.
This idea is better known as “yin and yang”. It’s symbolized as a circle split into two halves but with a piece of each in the other half. And in every depiction the two sides are equal, yet opposite. This shows how both sides must always be in balance with one another. If not, then there’s disparity and inequality. Imagine if the sun never rose, gravity disappeared, or water couldn’t freeze. Our view of the world would turn upside down because what was balanced is now unstable and unpredictable.
When complementary forces become unwillingly unbalanced a sense of injustice begins to grow. What was once a fair give-and-take dynamic has been replaced with a bias for one side over the other. Once this occurs the struggle to correct the equilibrium begins. Especially if it was done by force and not by chance.
