Understanding Human Tendencies and the Absence of a Doer

A little while back you mentioned Human Design (which I know very little about), and it made me wonder how a system like that can fit with the understanding you talk about here. I would have thought trying to fit our experience into some system would only take us several steps further away from reality. But maybe I misconstrued what you were saying in the first place, or else there's something I'm not seeing (very likely) that renders such systems helpful even in this understanding. Is it possible you could enlarge upon this, please?
