In a word "faith", and the human mind becomes capable of unimaginable feats.
While some of this may seem to have no rhyme or reason, not all of it is antagonistic, nor is it all being done for selfish purposes. While I am no fan of any program which would put ET at the head of any form of acclimation or rehabilitation types programs in a post disclosure world; I do feel there is a time and place for some form of open communication and possible collaboration with ETs.
When it comes to Higher Order Entities, I do know they watch and in some instances intervene at a tribunal type level.
Demon type entities are usually sought out, sorry but this is the truth of the matter. Whether this is done consciously, or subconsciously, may be up for debate, but a person's thoughts will affect their environment and drag them into whatever it is they are chasing after. Regardless of whether the thought process is to banish them, or to shake their hand, or even to study them for an academic understanding of their methodologies, this all leads down the same road.
A hijacked visual field at least for me was like an overlay, where reality was still present, but a simultaneous parallel space was being experienced. It is like being in two places at the same time. Mentally the two locations can be perceived as hundreds of miles apart, yet remain local to a single physical reality. As far as it not having an impact on reality or the training being useless for all intents and purposes, the easy way out is to simply agree. However, it does have a purpose, and it not only can but does affect the physical reality. A mind at war can bring down a tremendous amount of chaos into systems it understands and/or has access to. The opposite is also true, a mind at peace with itself can create and protect what it feels is important to its own environment. Many however do not have control either way, nor do they understand their own beliefs and faith have the capacity to shape the environment in which they reside.
At the end of the day it is a matter of choice, and our own active expression of these.
