In 1991, Wendy Grossman in the New Scientist criticized the parapsychologist Stephen E. Braude for ignoring evidence of fraud in mediumship. According to Grossman "[Braude] accuses sceptics of ignoring the evidence he believes is solid, but himself ignores evidence that does not suit him. If a medium was caught cheating on some occasions, he says, the rest of that medium's phenomena were still genuine." Grossman came to the conclusion that Braude did not do proper research on the subject and should study "the art of conjuring."[180]
Though historians like Kaplan and Matthews publish new information on divination decks every year, there are still many holes in the larger story of fortune-telling cards. Wolf points out that those who use cards for divination are often at odds with academics researching their past. “There’s a lot of friction between tarot historians and card readers about the origins and purpose of tarot cards,” Wolf says. “The evidence suggests they were invented for gaming and evolved for use in divination at a much later date. Personally, I believe they were designed for game play, but that the design is a bit more sophisticated than many tarot historians seem to believe.”

We can assist them in contacting us by learning to increase and raise our energy — by doing so, we’ll help in the communication by meeting them halfway. So, to answer the question, no, I don’t believe that anyone can become a medium. Rest assured, if you have the gift of mediumship, it’s likely to present itself in its own way and in its own time. My last piece of advice with respect to this question is on a somber note. I do not recommend this as something that you should dabble with. It’s such a serious subject and one that requires both delicacy and tact.

Do your homework when choosing a medium either for teaching or for having a reading performed for yourself. You might want to attend a few readings before deciding to go ahead and practice mediumship yourself. How long have they been practicing? Do they come recommended? Do they belong to an online community where they are rated? Did they have any formal training? There are official organisations and colleges that train mediums if you care to research them, you could study at one yourself! Always thoroughly check and ask for recommendations before joining any group, teacher or organisation.
Celtic Cross Tarot card reading predicts your future by reading the cards. This is different from prophesies using calculations of date, time and year of birth. Each prediction or card selection may not indicate the same result. The accuracy depends on your intention and concentration at the time of selection. Thus, it is very important to concentrate hard to achieve the most significant outcome.
