I want to just say thank you for sharing this information. Whether or not we know certainly about distent past populations emotions/feelings I may disagree. (Based on population and documentation, if by chance you remember your sources I would appretciate your response.) I agree that it's a way to build identity, but disagree on discovering true self. Some discoveries are being made on how we see energy, and how deeply connected conscienceness is. (by this I mean connection to everything we think of as reality) I seen these comments above/below, so I wanted to show that there's at least one other self who could show "open-ness?" I wish you well on your discoveries. Expantion and love. (ps. Unconditional love, now thats a near mystery. Love with no reason. That's facinating.)
