Someone recently asked if it was a good idea to sanitise the Tarot deck before use, to remove "negative" cards. The following represents my thoughts on the subject:
Nope. Not for the very young, not for the very old.
As to "sanitising" the deck to make all the readings happy-happy-joy-joy, well, you might as well buy a Doreen Virtue deck and have it done for you before purchase, if that's all you want from a reading.
I've had a number of traumatised clients (and seen a number of internet discussions from people who had been throught the mill), who uniformly said they didn't like happy-happy decks that didn't reflect reality.
Every time I read for somebody, I set about discovering people's problems and bringing them to their notice - then set about finding potential solutions so that they can repair their lives. With a deck that has had cards like Death, the Devil and the Tower removed, I simply couldn't function to help people. I'd have to talk meaningless puff, as some other readers I know do.
This means that, in the absence of being able to truly identify people's problems, I can also truly identify no cures, no courses of action that they can take to change things for the better.
I did a reading just today for someone in late middle-age who had very severe problems. If the only cards my deck had to offer were all happy-happy-joy-joy cards, I wouldn't have been able to detect what was really happening for them in their life, nor the emotional impact that was having on their inner world. Without that information, I would have been able to make no constructive suggestions, specially as so many of these so-called "negative" cards hold within themselves hints to their own solutions.
Do people really want readings that change nothing and don't help them? I don't think so. At the end of the reading, this person left, giving me a hug and promising to come back and let me know how things play out after they put into action some of the suggestions that the reading brought out. I simply couldn't have said anything important or helpful today if my deck had had its teeth pulled.
