 the mandate of heaven, I mean, however you want to call it, that there's this higher law which you can't bend, the laws of the universe forever, without them bending back on you eventually. And they swing back to where things belong. It's part of the homeostasis of nature. Not only do we look for that in our bodies, but nature has a homeostatic balance. And you push it too far one way, it has a way of pushing you back.
