As with most families, there are elements of tribes that seek to control, manipulate, and even destroy anything that grows beyond the tribe's ability to control. Banishment eventually becomes the tool used in an effort to shame the uncontrollable member.
I am the banished member of my family in that I refused to allow anyone to control me, my thoughts, or my way of thinking. I notice that those relatives in my generation who still ascribe/ submit to this tribal mentality and thinking seem unhappy, always spreading that unhappiness in every way possible.
One thing have noticed in my life's journey and study of people and their belief systems is that tribal mentality, commonly called "group" think seriously holds many persons back from ever attaining the ability to independently, logically and rationally be able to THINK and/ or REASON.
Tribal mentality is equivalent to first chakra energy and lower level thinking. Religion falls into first chakra energy and tribal mentality, and tribes seek to protect its own members, sometimes to their members own detriment after having controlled their members thinking ability.
