In the world, there is duality, a polarity, two forces that forever try to find a balance, an equilibrium.
In the world, could we have positive without negative, wind without calm, rags without riches? Without a polarity, would life arise? All things seem to possess a certain polarity, including good and evil. One concept, one substance seems to need a space that opposes it in some way or defines it to exist. Within our bodies, minds, and spirits, this duality makes our lives, and is the force behind every action within it. A balance of things gives stability, imbalance brings friction. Many ancient Greek citizens tackled this issue. How do these forces affect our lives, and how can we live optimally within them?
