Vin, according to the theories of OTIII, "blowing" doesn't mean that the being "as-ises". It "leaves your space". As it leaves your space, the "feeling" is similar to "charge blowing". And, from a certain perspective charge IS blowing - just not yours - but up to that point you incorrectly identified the charge as your own. That is all. It (entity) is no longer there to affect you from the level of any other "reactive mind".
What gets BLOWN is the entity's "unconscious and chronic connection" to you. You don't as-is anything other than the entity's connection to you and your own previous mis-identification of the "bank" or "energy", as your own. Like anything else from a Buddhist slant, it is just another "thing" one has falsely identified with that needs to get sorted out. I suspect that it naturally sorts out during valid meditation techniques designed to unravel mis-identification. Of course, Hubbard would claim that NONE before him EVER found a way to address this SEVERE problem. Yawn! I doubt it though. Hubbard makes it a big deal. I doubt it is really that big of a deal.
I don't necessarily subscribe to all of that, but THAT is the theory.
As I have said elsewhere, there are "entities" EVERYWHERE. Anyone can "tune into them" if you so desire. It becomes a bit futile trying to "help them all", as some others have implied in this thread, because there is no end to them. To me, there are many things that can be helped right in the world around one. There is no need to start digging into "invisible realms" to locate areas that have problems and could use a helping hand.
Also, I have exorcised "ghosts" before, though in these cases, they weren't "BTs", but recently dead humans who had suffered traumatic deaths, and who were "stuck" in the incident and location of the incident (due of course to his or her own consideration about it all).
When I was doing my grades I spent a few weeks putting my attention "out there", and found that "living entities" exist at every level of creation. If one didn't "filter" it all out, all of the endlessly available "thought patterns" coming from these nearly endless number of buggers, you would be bombarded with constant "messages" and "energy", making any living of any normal life entirely impossible. Simply, it just isn't relevant. Of course, one can go out and "handle" and "help" them if you want to, but the evolution of these entities never stops, and they will "progress" regardless. The physical body has very limited sensory appartus, that while tuning in to certain frequencies of energy, necessarily OMITS the MAJORITY of ENERGY that is actually out there and available for perception. But, other sensory apparatus are required to "tune into" these other ranges of energy.
If the BTs exist as Hubbard says, as largely unconscious spiritual beings, who were "once human", then who knows what else might "free them". For instance, I sometimes do a meditation where I fill myself with white-yellow light of amazing "love". It is affinity out the top of the tone scale. I invite it to enter every aspect of my space. Things always pop and snap and "blow" when I do that. I don't doubt that this simple exercise enables many to vanish. If you understand that when I do this I am overwhelming all in my space with complete "granting of beingness" and "well-wishing", I suppose that some of these buggers could "wake up" and head off to new adventures.
Also, yes when I audited OTIII, I also treated them just as any other "person", with auditor code IN, full granting of beingness, and my attitude was to "help" them overcome whatever was keeping them "stuck" where they were. But, they will ALWAYS be there. I mentioned this on another thread. The ONLY possible EP of OTVII is that one no longer has any attention on or tendency to go the effect of "other life forces" in ones space.
They will always be there. Who cares? But that IS the problem! Many people have a real big problem with other "entities" existing in "ones space". People DO care! And thus, that type person needs to spend many hundreds or even thousands of hours auditing what really shouldn't be a problem at all!
but here is the next part.
