Even though I believe intuition is key to tarot reading, I do A LOT of studying and memorization, though not necessarily of keywords. Through trial and error I have found that the structure of tarot is needed (for me) to focus my intuition so it can really soar. As an example, I get absolutely nothing but joy in pretty pictures from most oracles, but I can read even the crappiest tarot to mostly good effect. I feel the structure I have learned and continue to study is the key to tapping into my intuition. Within the bounds of that structure I have more freedom, in an interesting paradox.
Not everyone has to read this way, but some people do much better this way, and it is as much a disservice to them to try to make them believe study is unnecessary as it is to a purely intuitive type of reader to force them to study. Although, I really don't understand why meditators or intuitive-only readers choose tarot, which is not meant to be an inciteful comment, just an out loud musing. The more tarot-ers the better!
I'm glad you've found a method that works. Good for you
I think the fact that the majority of Tarot Decks have pictures may be a good indication that they were not meant to be simply 78 cards of keywords. If one is simply, (I'm not saying you are) learning by rote a bunch of associations with each card, then what is the point of all those pretty pictures? Do you think it's to decorate the keywords so the card is not so plain or do you think there is another reason such as triggering associations from deep within the unconscious?
If it was as simple as learning a bunch of associations we would surely all be giving exactly the same meaning to every card which surely cannot be right.
I have found that my least effective readings are when I only see the supposed meaning behind the card. For example, Ace of Pentacles. The Pictorial Key says that the Ace means: "Perfect contentment, felicity, ecstasy; also speedy intelligence; gold." When was the last time you told someone that they were coming into gold or they were going to achieve "perfect contentment"?
With the fact that an Ace is a beginning and a Pentacle is associated with the material there are a whole bunch of meanings associated with this card depending on the querent and the other cards. It may actually mean something totally different because the image on the card has triggered something in either yourself, the reader or your querent.
Sometimes the strangest least plausible stuff is dredged up and you come out with things you have no idea about that the card is a springboard for.
Tarot is not an exact science and that is its wonder. I first began to actually read Tarot when I didn't scrabble for meanings and really listened to myself because the cards are a key to what is inside you and that is what the images are there for, to access something deep inside yourself.
I have handed my cards to people who have never touched a tarot deck in their lives and they have given me pretty good readings. Nothing mind blowing but a good basic reading none the less.
