I'd like to know, too -- and I don't want to go research it on the Internet in case they send aura-control worms back to my computer.
I mean, look how well L. Ron's theories have worked out for Cruise and Travolta.
He claimed that if a tester would make a tiny 'clam' with their thumb and forefinger and rapidly open and close it, many or most non-clears would react violently at the engram. It would be too disturbing for a non-clear to watch a Scientologist's little finger 'clam' to open and close.
He claimed many non-clears would suffer severe jaw pain from watching, pain that could last several days.
As a result, former Scientologists and those who debunk Scientology refer to Scientologists as 'clams' and a gathering to discuss Scientologists or a website about issues with Scientologists as a 'clambake.'
Scientologists are not humored by being called clams.
