" Destiny's bank is inexorable, all accounts must balance."
-Dorothy Fuldheim, A Thousand Friends (1974)
How do accounts balance? It's simple - what you put into it you get out of it. It's just like the law of cause and effect. It's a principle of nature - and that's just the way it is. In Eastern philosophy, the accounts may not necessarily balance in one lifetime, but over many lifetimes. It's looking at that big picture again. Life may not seem "fair" at one particular time - but it generally is when you look back over the long run.
