Thank you, Titus for the article.
Since introspection is one of my favorite hobbies, I´ll try to share my opinion and experience here.
I do believe that part of our current personality is just an adaptment to the body, cultural environment and upbringing. You can call this adaptment whatever you want, I´ll call it ego. There are people whose egos are huge and it totally covers the soul or true self. They don´t really know who they are. When you think that your PL-self was very different from your current self, you may have had a very ego-driven life back then.
Then there is the soul, your True Self. It won´t stay constant but will evolve and mature. Our experiences change us. I´ve also experienced a major personality change in this lifetime.
As a child I easily found a certain collection of archetypes inside of me. I believe they are an essential part of my True Self. For example, although I am a woman now, I was always aware of a strong masculine side in me as well. It was easy to find an Aristocrat, a Scribe, a Hedonist, a Horseman, a Natural Child, a Judge, an Artist etc. Later on, I found more of these, like a Knight, an Axe Killer

and a Mystic. I think that these archetypes are my PL-personas. My current life as a scientist will be one of my archetypes in the future.
I believe that these archetypes will always be there, from an incarnation to another. How you live with them and use them in your current life, is another thing...
