Joe Dispenza offers a simple and effective scientific approach of the karmic law "what comes around goes around". Your life is determined by your inner state. That simple statement has no effect unless you genuinely believe it deep down your being. But we are conditioned to thinking that the only truth is that comes up in science book. Quite luckily the most recent development of quantum physics confirms that rule. The problem is that quantum physics is out of the reach of most of them.
