Only have time for a brief post..
Tarot cards (can, did and do) have meaning without astrological or Cabalistic attributions, many decks have been and are today created so, and used so.. the Majors are much more profound and each is more complex than that of representing a Hebrew letter or astrological association
Historically, from what is definately know, ..With Early Tarot (ca. 1420 Italy ) there is no (or no significant) attribution of the Kabbalah/astrology to the cards (though it speculated by some, that Tarot was the Kabbalah system represented in cards, presented as a game to hide it, to save the knowledge and avoid the Christian suppression etc.)
France (1700's, possibly as early as 1672) - appears that the cards may have philosophical/metaphysical symbols, though meanings are lost and the modern printing method (1760 and definately by 1880) reduced/lost symbols and the original colors (which are very important symbolically) because of the 4 color limitations and mass production etc.
some will disagree with the next paragraph, but to me it's definately a correct distinction for 3 branches....
Kabbalah - Jewish mystical tradition, used for insight into scriptures, and a path/framework to mystical insight/experience, insight into Reality, guidance, validation etc.
Qabalah - generally used to indicate the use of Kabbalah as an occult and practical magical system;; used by Hermetics, Gnostics, Neoplatists, Rosicrucians, Tantra, Golden Dawn, Levi.
Cabala - Christian adaptation used mostly for insight into the scriptures (and some attempt to use it to "prove" Jesus was the Messiah)
Most astrological associations come from the Kabbala sources such as the Sepher Yetzirah - there are various versions and they have differing attributions for the astrological/luminary symbols ;; Kaplan documented variations between versions.. signs/planets are assigned to the Hebrew letters and Qabalist used that (by assigned letters to the cards) to arrive at the astrological attribution for each card, even the letter assigned to the each cards has varied widely with different authors, and no system works 100% convincing (i agree VIII and XI must be swapped, but this is because the INTENDED original order of the cards was not necessary what was printed, it was scrambled to hide the knowledge and I have verfied that Tsade is incorrectly attributed to the Star (afirming Crowley, though I didn't believe that he was correct about this until recently) ... therefore the attributions do vary (though Levi's certainly is "wrong" perhaps the offset was intentional) ... now we begin to see, how complex and difficult this is
More serious... even if you resolved the Sepher Yetzirah's "printed" versions and attributions.. the result still may be VERY wrong... I have been taught (as is know publically, no secret, but usually ignored).. that the Kabbalists would NEVER HAVE PRINTED or DOCUMENTED on PAPER the correct attributions, they were intentionally scrambled.. they were printed, but in the personal tutoring of the true secret knowledge, the student was given the key to unscrambling the attributions.. so the arguments about the printed version, attributions is very tenuous... and then the current assignment of the Hebrew letters to the cards is certainly not 100% correct... so the corresponding attributions are certainly wrong in some or many cases... (I PROPOSE THE FOLLOWING FOR ANOTHER THREAD, let me describe in detail the energies of the illuminary object.. without telling which one it is, and then have Taroist with much reading experience, tell me which MAJOR ARCANA goes with that description... would be interesting to see what the consensus would be for the attributions then) ... even so, each person arrives at their own insight into each card and the readings will vary from one person to another to reflect the meaning for that person.. so asking someone to interprete your spread is only helpful to a slight (commonality between the two of you) degree
this only scratches the surface, and I've probably errored in a detail or two, this is off the cuff, I have thousands of pages of notes on cards, meanings, history, attributions, symbols on the cards (several versions, Thoth is my main deck) and the meanings and attributions for those.. (tons of astrological, historical, mythological, religions (Egyptian, Greek etc.), and metaphysical.. it will be printed within the next year as 1 or 2 books.. (I'm author of many books)
(ALL THIS is ONLY my opinion of course, based on years of research, others have differing options of equal worth and every point can be disputed.. I studied Kabbalah for 7 years (Jewish Rabbi who "adopted" me), I spent over a year in Italy (on musical scholarship with my wife), visited France, Germany .. spent 90% of that time studying the history of Tarot, examined many original sources; was a Buddhist monk, studied Vedic and Tibetan astrology in India/Nepal for 2 years; during which I completed the Abramelin retreat (6months in Nepal monastery) and magickal study) ... I do believe there is some new breakthough information that will prove or at least suggest that Tarot is much more ancient that 1420, but currently I can only go with the solid research, showing it originated as a game, wise people immediately recognized the Architypes and the profound possibilites .. and adopted and evolved the Tarot over centuries to where we are now..
>>>also I believe that Vedic astrology is far superior and more accurate than Western astrology, I have revised my attributions to Vedic/Tibetan astrology attribtions
