Is this based on LRH only?

Hank Levin was never in the official Scientology organisation. He was taught by one of the famous people in the free zone in the eighties in USA (I think the person who organised the fourth of July meetings for some time, name temporarily forgotten). Was probably based on Ron's work only, on that basis he has formulated a number of rundowns. It should be noted, at least amongst us, that the word clearing was widely advocated in the eighties as a substitute for the word Scientology in using Scientology, because of a supposed antipathy towards Scientology amongst the general public.
