There's a problem with taking something as subtle as the internal workings of a human and saying "aha! I now understand what the effect of this is or why that is happening". We seek simplicity and conformance to our mental models, but nature doesn't have those constraints. It's naive to think "I've figured it out". And, that's a good thing. Many times desire for explanations is just to make oneself feel in control. Just being intimately exposed to that is therapeutic on its own.
