Keeping Scientology Working - Altered materials on this site

The PDCs audio lectures, are the recent (GAT) versions which have been altered by the CofS post 1990. As an example PDC 15 - The Logics: Infinity-Valued Logic, LRH states in the original audio lecture 
"You can get a much better fee - I tell you as auditors quite frankly - it ... its much easier to get a great deal of money out of someone who's on a down spiral into becoming MEST than it is to get money out of somebody who is going on an up spiral toward becoming theta."
This is written in at the bottom of page 253 of the PDF transcript, but is edited out of the recent audio version by the corporate CofS. The statement is best read in context.
There are other alterations appearing in these audio lectures which I will post when I get a chance.
