Yes, I am sure much has been said here and elsewhere on the subject. I just feel it wouldn’t do any harm to start another discussion, with the same or different people, getting different perspectives and circumstances. Plus, I like the interactivity. So if you don’t mind…
When I saw that the OT III materials were outed yet folks weren’t freewheeling and dying of pneumonia after obviously understanding the matrials, it started a chain reaction back to my earlier days and beginning courses. Then I came forward, asking myself along the way, what would I have to believe in order to get to the point I’d be giddily ready to start auditing OTIII, which I had already completed. The belief was that the bts had to be found, and released along with their banks. Banks which I once believed existed. So finding them and making them blow, was easy. Was any of it really there? No. Was I putting them there? Yes. Did I believe I was cleaning myself up? Yes. Was I happy and proud to do these and the higher levels at the time? Yes.
As Olska has said, but explained a little differently from my perspective:
Same with dianetics processing. The pc has studied the theory… knows what to look for. Upon command, the pc starts looking. Sooner or later the similarities will match and the chain will blow… an exercise in creating ones own incidents. Underlying all of this is the belief that LRH’s techniques are true. To “prove� it, the pc runs the process, and inserts the incidents where LRH has said they will be, and BAM, more “confirmed� belief. Other than LHR saying so, is there any proof that we ever had1000s of chains with real, active engram content? No. Only that pcs can find them (create them) when driven down the track, knowing he will stay down there until an incident of similar circumstances to what bugs him in the present can be found to match.
The exact same technique would work for finding bad mommies. If the theory was that somewhere, down the track, there were some really bad mommies one needed to finally confront and blow to release present problems, one would indeed find them, and say, “bad mommy� and blow the visual just created, come up to present having kicked some bad mommy ass. If it was believed by the pc, bad mommy always held power over him, why he’d be pleased and happy to find them.
Convince the pc first (insert) belief that (inserted belief) was the “cause�, send the guy down the track after it… Bingo. Repeat for a few months or a few thousand chains.
After realizing that it was I who was creating it all along… that the entire bridge was in fact a dancing act between ethics enforcing belief, and my compliance to LRH’s vision of what was “wrong� with me… I became instantly humiliated.
As Mike has said, there is no single “why�. There is a multitude of reasons, all of which must be believed.
1) I am a worthless WOG
2) Scientology is the only way
3) Hubbard figured it out
4) Hubbard’s tech is scientific
5) Hubbard’s OT
6) OT’s have power over everyone
7) The tech works

Sp’s are the cause of the planet’s spiral
9) Sps are real
10) I’m special because I believe in the above
11) Earth is a dumping ground
12) etc., etc.,etc.
Underlying disbelief in any of the above (and the hundreds more not listed) is fear.
IMO, overcoming the experience, with lessons learned, one can become a much better person than he or she every could have become as a limited, shut down (yes selfish) individual while caught in the trap. “What’s good for the greatest number� depends on what your definition of “good� is. Scientology governments, no more elections, firing squads for declared SPs, Ron’s office in the White House, MC types stomping about… are all “good� with the above beliefs intact.
