True Self vs False Self: A Perspective From A Person Trained in Biostatistics

I always wondered about phrases like, "If you meditate this way, you will connect with your true self." To me this somehow implied that right now, not all of me is my true self, but something else. Some mixture of true and false self?

I guess people who came up with this idea had a logic vastly different from mine. A person like me would ask for percentages (+/- SD) of changes between the True and False Self inside a person before and after meditation. Also, I would have asked to strictly define the criteria for "true" vs "false"; who exactly would be measuring those, and how, and are they qualified to do this...

Better not get me started.
