The process where it manifests from? there are some basics understandings codified in the structures we both meditated upon. it seems to me to be well explained via am impression abstract structure that is reasonable within its metaphorical like ness to the actual of our sheared experiences.
the circle of the enneagram reminds me of a field as like a continues string, i can think of it as a frame work scaffold system a flexion of wave energy activities. And within that nano vibrating flux is the oscillations of selfs phenomenological experience.
So we have codes and patterns that we have codified in the endeavour to manifest a full science a map Human-Psychometrics. And our very own bodily structures or knowledge of the medical and anatomy of our physiology.
There are structures and pathways between the codes within the modes we utilise in understanding the MBTI Enneagram Hole Brain Model and Number Patterns.
i would not suggest that a full framework understanding of psychometrics needed for transformational work at the individual group and social activity level is out of reach. My interest in the enneagram and mbti and other structures has always infused by the knowing that authentic synergy development is posable, by authentic i pitch the level at levels 1, 2, 3 of the levels of development. Basically Level Three Of The Levels Of Health/ Development (Riso,Hudson) LEVEL THREE - The Level Of Social Value.
But anyway Si and where it manifests from Body/Mind/ physics chemistry electromagnetic source. Yes you are correct where it is manifested isn't recognisable and if so it is not discussed locally smug laypersons on these discussion boards.
what i do know is that the I , E , P , J ,, S - N - T - F , S&N - T&F , Point-Eergy , Subtype , tritype , Hole Brain Type , Tri-Fix , a couple of my models , work together in patterns as like a structured framework mechanical mechanism. My gut feeling says that chemistry genetics and a science of electromagnetic energy and other fields collaborating will yield a testable out come a synthesised model of mind within a machine. Some time of but not impossible for the curiosity of the Human Mind.
