I agree with this. I used RW at first and found the Thoth minors not 'visually descrptive' enough. But as I started to do a lot of public readings I realised the RW images were actually restricting my interpretation. The more 'abstract' or 'impersonal imagery' on the Thoth began to trigger more of a 'feel' for the energy and that was modified by other energies present and the clients situation and I was able to combine THAT into its own visually descriptive picture.
With RW I was trying to fit the persons unique situation into the RW visual image.
So I feel the Thoth really helped me develop as a reader.
[ As far as a sytem of Hermetic and magical/philosophy to study (aside from the decks use as a divinitory tool) I find it unsurpassed and have studied the system with fascination (and great help and assistance to me) for over 30 years.]
The Thoth actually made me almost give up reading, actually, at least in the way I used to. I suppose, without meaning to complement myself, that now I "divine" while before I used to "tell fortunes," and the difference is like night and day.
It was only about a year and a half ago that I picked up DuQuette's book and started looking at it really seriously. At first I just read it while looking at the cards and after a while of that took a few months off to learn the rudiments of Qabalah. I read the Book of Thoth, but didn't study it, as I am doing now. That took a while, and now I'm back, analyzing each card in what is probably a very basic way, through the BoT, the Tree of Life, assorted mythology as well as the mythologies of the astrological signs and planets. Slow going, but I'm not going anywhere, and this is my first in-depth look at it. Each card takes me about two weeks and innumerable pages of musings until I
think I vaguely understand it, or at least gain the knowledge that I don't.
It has challenged me and my innate preconceptions to such a degree that I can't even describe it. I can't tackle the Book of Law yet and do it justice, and although I dip into it now and again as necessity arises, I'll conduct an in-depth look after I'm done with, at the very least, with the preliminary survey of the majors. That should take me, at most, another six or seven months, considering I'm on Lust. Of course, after the BoL it will mean going back to the cards all over again, but that's part of the package.
But this must be the trite ramblings of a N00b to someone with 30 years under their belts.
