As I understand it, the Excalibur manuscript was nothing more than a precursor of Dianetics. Perhaps that is just the "Church Line" but apparently, the contents of Excalibur is laid out in Dianetics. This was discussed a briefing which I just happened to see, years ago. I think it was delivered by DM. Don't recall exactly.Thanks Veda. That's very interesting. And a well writen synopsis. I guess I will have to contact Gerry Armstrong. Gerry ,if you read this, please comment.
