I was blown away by this yt video because this spiritual teacher clearly and calmly describes very early interactions with the mother and explains if there is not enough support from the mother x will occur with x qualities and he literally said something along the lines of "introverted intuitive" - he said it slightly different but almost word for word.
I've watched about 30 minutes of the video and it's very interesting to hear these thoughts expressed in the terminology of a different matrix of conceptualisation to the Western ones. It's such a complex issue so my reactions are just immediate bullet points rather than deeply thought out responses.
I don't think that our type can be determined as a result of trauma, but is determined by our biology in the same way as the colour of our eyes or our handedness. Just as our handedness can be overridden though, so can our type by the way we are raised. I can easily see how a traumatised infant can acquire the habitual behaviours of (say) an introverted intuitive even though they are not one. They will always be dislocated in this, just as a left-handed person will always be an inferior right-hander. I suspect that there are quite a few folks who type as INFJ but aren't - they are living the outcome of that early life trauma. Their cure will include taking on the behaviours of their true type - this doesn't necessarily mean knowing all about MBTI but changing the way that they habitually think, feel and relate to others.
This isn't just a bit of theory from me but from experience, because I spent the best part of my life acting as though I was a dominant Ti even though it's Ni that's my home. I can only express this easily using the terminology of MBTI, but my inner experience is not bound up with that terminology and goes back to my childhood from about 8 years onwards. I did it not in response to problems with my parents who were pretty awesome, but problems with my peers.
I think some of the 'adept' responses that he talks about need to be treated cautiously - in the sense that they may be a reaction to trauma, but they can also be a response to insight. I don't find my own mystical experience, which goes back to my infancy, a reaction to life being shitty, but a response to the glory and the love that I have seen and felt deep within the world I have been born into. I don't belong here and I'm passing through, but that doesn't mean that the world is wrong or has harmed me - it just means what it says on the tin. Of course people may respond to childhood trauma in those ways, but they are experiences that are their own thing and not simply a response to trauma.
I had good parents, and I have inherited a lot of my spirituality from my mother, so I cannot imagine what it has been like for those of you with parents that have not given you a safe childhood. It's not just in terms of the parents who are dysfunctional. My mum was INFJ and my dad INFP - I can only think with fear and trembling what it must be like for an INFJ child born into a family of STs who try and form you into their own image and likeness.
Maybe it's wishful thinking, but I have this strong feeling that salvation lies not just in dwelling on our parents in the past, but in making sure our own children are given the childhood and the parents we would like for ourselves.
