It seems that all the micro and macro level happens by accident. But it is actually that each system is unique, and the behavior of subsystems that make it must be exactly such as to keep schemes. The system can be disrupted, it depends on our health to spiritual or physical level. The laws are the same and at the macro level. We are inalienable by nature and because we have made of it. In human being, nature and the universe, everywhere is the same law. Nothing is accidental.
