AHA! Oh wait, Crowley already took that title...sorry.
I just got a response from someone in the Gray group, a former student of Gray's. He told me Gray liked working with the Waite-Ryder deck! I KNEW IT! The book, "The Talking Tree," uses that deck for analysis. This student also told me when he worked with Gray, Gray insisted he start with blank cards, as described in the Ritual book.
So now I really need to sit down with all of this and sort it out. The Waite concepts, as we all know, are based on the Golden Dawn, yet Gray himself devised a new set of connections based on his own thinking. Still, the images on the cards are assigned astrologically, and that is important in all Qabalah work (except for that one person who doesn't use it, and is going to counter post me. LOL!) I find the astrological assignments mostly decent with the deck, or at least most of them. THE CHARIOT I never see as Cancer, unless the charioteer has the crabs or something. Hard to tell with that armour on. And THE MOON and Pisces, well, I suppose...But most of the others seem pretty okay to me.
I have to sit down with this information and see what's up.
If I can figure out how to do "it", I could post an attachment, a chart I made of the Gray path assignments on the Tree. I made it in CorelDraw, but imported it into a Word file. Let me see if I can figure this out. If so, I will post it for all of you, those who do not have access to a Gray book.
