If this practice of exclusivity is not observed then it is possibly the retreat into reclusiveness being observed instead.
Thinking of it as an eyeball – the iris is a means to gain entry into the brain, it does not take much to sully it if a person is unwitting/unwilling witness to anything they would contend as right…, so soon they concede.
This is why it is known that people are intrinsically good – for when it is good in the brain, right in the eyes and there is an instance of bad/wrong before them, the person reacts like they are infected whether through articulated account, physical response or [mental] comprehension.
I penned a piece called ‘Never Ending Embrace‘ detailing a parasitical entity that may be a multi-dimensional gore in Creation – As it has affected humans it has been personified, as a person comes to understand it on their terms, it pertains to the senses, as it pertains to the senses – so it makes feelings unbearable….
And so in earnest, man [re]establishes an exclusive area and once again begins to filter content with an aeons-long yearning for everything right & in it’s place…..
I was going to add a [symbolic] ‘Currently ~ing’ although decided instead to post the results for the search term ‘purity‘
