Barleywine: Indeed, with the proper literature, Debauch is a much more clear and concise concept to grasp. Though, I'm sure the Book of Thoth is equally convoluted in its own charming way, I mostly rely on third party authors to give me the lowdown on Thoth, such as Lon Milo Duquette. After attempting to get through the barrage of pages that Crowley wrote on The Fool card alone, I decided that Thoth would be a parallel pursuit alongside the RWS.
Ruby: It sounds like you are doing just fine with your interpretations, and most really aren't experts in alchemy, gematria, numerology or even Kabbalah (my chosen spelling) just to read the cards. Like some, I tend to look at Tarot as a learning tool more than a divinatory method, and find all aspects interesting as they do link as far as you wish to learn. I certainly didn't mean to hijack this thread, however. But the 7 of Cups is quite a unique card for many reasons stated thus far.
