I'm not convinced that treating the true you (higher self/soul/sprit) as a separate entity is a good idea. It seems to promote disconnection.
I think the real point of all this physical existance stuff is to help you grow your soul, by having an earth bound reality. Why we can't fully integrate with our true self while in this physicality, is part of the mystery we all are trying to solve.
All of us here interested in PD seem to be searching for the same answer, but are asking slightly different questions. Unfortunately and ultimately only you will ever be able to answer the question for yourself.
