It is based on a method of deep trance induction based on a technique described by LeCron in the 1940's - as a deep hypnosis technique - LeCron said that all you have to do to induce a deep trance is cause the person to repetitively imagine something that is not physically there that is in motion.(see note below)
This is the method used on the "The Clearing Course" and some 'OT Levels' and other supposed 'levels' in scientology by Hubbard.
It is one of the methods in scientology shared with Falun Gong, and more importantly the fanaticism (Hubbard uses the word 'certainty' to describe the same result) of its adepts is, dangerously, of similar intensity.
(note) Try this innocuous self induced deep trance using this method if you doubt my words... Because a deep trance causes a pain free state, Hubbard called this "clear"... you will find this both pleasant and relaxing ( direct suggestion).
Relax in a comfortable chair. Imagine an orange basketball rolling slowly across a table towards the dge. Anticipate it reaching the dge and falling off.. it then falls off the table, then bounces repeatedly on the floor and goes out the doorway, out of sight, but you can still hear it bouncing away as the sound fades away to nothing. Repeat this 'excercise' or 'process' a few to a dozen times... Relax and enjoy the benefits of a self induced trance state.
Now reach into your wallet that contains the money that you got from your BANK (which you simply must get rid of because the BANK is the dreaded REACTIVE MIND) and mail me a check for $100..in compliance with the Ferengi and scientology doctrine of exchange.
