Dark and Light.
Why do things have to be such absolutes?!? Dark is associated with evil and light with good. You know when the two come together, they create a tapestry-like no other. We all have been witness to some fantastic and beautiful sunrise and sunset; the darkness fills the night and brings out the stars. The sun kisses the moon and brightens her up! So you see the magic of the universe is in everything and everyone. It all has a purpose, and how we choose to look at things is really up to us.
