XII. Law of Duality
Any concept or force may be divided into two totally opposite concepts or forces, each of which contains the essence of the other. Opposites can be defined only in relation to each other.
I have always believed that for the most part this is true. The idea behind this is very much like cause and effect. I know that so many people believe in 'karma'. I do not really subscribe to this idea as much as I do cause and effect. The reason I believe in this is you cannot, in most cases, have a cause without and equal and opposite effect. If you drop a pebble into a lake there are ripples... those ripples spread out across the surface because of your actions. They do not effect just you but all those around you and those around them and so on until the ripples die down.
