Our lives are in a constant state of battle between chaos and order, of abandon and constraint. One is always looking to dominate, to utterly consume its other half. Some of our ancestors believed that only through balance could we achieve happiness.
For without order, our lives would descend into mayhem. Losing control means we become boorish and instinctive, losing rational thought and objectivity. We surrender our humanity and give into our base selves forgetting kindness and joy.
Without chaos, we bereave ourselves of spontaneity and impulse. Our lives would be consumed with the mundane, unable to escape the prison of our existence.
The dance between darkness and light will always remain— the stars and the moon will always need the darkness to be seen, the darkness will just not be worth having without the moon and the stars.
