It seems the whole world operates on an almost magnetic push and pull between dualities. There is the obvious night-day, life-death, black and white. Human emotions are also described in opposites such as happy and sad. But it also seems to be that society itself is operating on dualism - a push between ideologies, good-bad, left wing and right wing. The way we choose to live appears governed by the order of the world we inhabit; darkness and light.
