Tarot Myth:
That a sitter doesn't actually have to tell their reader the question they want answered. They just need to touch the cards while concentrating and the cards (and the reader!) will receive the "energy" of the question. And obviously a reader who needs to be TOLD the question just isn't very good!
I was taught that the first time I ever touched a tarot deck. Ironically, the person who taught me that you can't voice the question didn't have a problem with me touching and reading for her with her deck (breaking two other myths). But when I dared to ask how I'd done my first time, she seemed affronted that I would hint at the question.
I also read in a book recently that you shouldn't read with illustrated pip decks because they cloud your intuition to the real meaning (which according to this book was usually opposite traditional meanings, i.e. the 5 of pentacles was financial fulfillment according to him). He also insisted that you shuffle with the non-dominant hand. Since I'm ambidextrous, I wonder which one that is supposed to be?
I've also been told that if I give an accurate reading, it's not really that the cards worked, it's just that I created a self-fulfilling prophecy . . . never mind that things that were not in my control still happened or that the past was described with an uncomfortable degree of accuracy or that doing three readings in a row yielded the EXACT same cards, even after thorough shuffling.
Edit: these have been hilarious to read through! They made my day so much better.
