I think it depends on your personality and your personal 'glorp.'
I was first given 2 Tarot decks when I was 12 (one to use and one that was a hand-painted family antique) by my great-grandmother, who read Tarot. She taught me a bit, but I lost interest for a year or two, and she passed away, before we could get into really ‘deep study’ or anything. So, while I have some of her meanings, and a whole host of readings she recorded and predicted for my life – many events of which have come true, exactly as she said in scary ways, years later, so the lady was good – I never really learnt ‘her’ way of reading the cards. Nor do I think she wanted me to.
I don’t think she ever read a book on Tarot, but she read history and fairytales and had a suitable knowledge basis for astrology, numerology, etc. She knew and expressed many of the things that are in books, and because she had been handed the same deck she handed down to me, and because she had been taught by others, she had full confidence in herself by the time I knew her.
The books on Tarot do two things for me – they build understanding and they build confidence. Comparing decks is much more helpful for me to develop ‘meaning’ (and studying history, symbolism, numerology, astrology, etc) than the ‘Keywords’ are. The keywords are rubbish, in my opinion, but at the same time – comparing keywords from different sources brings new meaning, too.
But the greater things the books do is build confidence because I develop confidence through knowledge. Seeing decks builds confidence. Learning the numerological and astrological forces of the cards builds confidence.
The ability to read the ‘glorp’ is there or it isn’t. You can or you can’t. Maybe everyone can. I don’t know. It’s already there, waiting to be unlocked. What unlocks it is going to be different for all of us. For me, it’s knowledge. It’s seeing comparisons. My motto used to be ‘read but don’t buy.’ I’d sit in bookstores or libraries, reading every Tarot book I could. A lot were rubbish. Some were good, and I re-read them over and over to memorize bits and pieces. I could have looked at the cards for 100 years and not unlocked the ‘glorp’ that some of those books unlocked. I could have done 1 million readings and not unlocked the ‘glorp’ that some of those books unlocked.
So, to me, knowledge doesn’t hinder the ‘glorp.’ I don’t always stick to the knowledge of the cards in my readings. In person, I rarely do. I’m actually trying to learn to be a bit more ‘literal’ right now, because I tend to be ‘left-field-y’ at times, and I’d like to find balance. So, that’s my current ‘goal.’ But ‘knowing’ has never prohibited me from seeing, because the knowledge is fluid and evolving. So, I guess it depends on whether knowledge distracts you or not. For me, it’s not ‘distracting’ to notice a symbol.
For example, I don’t always notice each symbol, so when I notice it, I realize that’s ‘glorp’ seeping through and telling my logical mind to connect because it can’t quite give me the words in ‘glorp.’
Wow, that was a lot of times to use the word (no-word) 'glorp.'
