In 1781, a French Freemason (and former Protestant minister) named Antoine Court de Gebelin published a complex analysis of the Tarot, in which he revealed that the symbolism in the Tarot was in fact derived from the esoteric secrets of Egyptian priests. De Gebelin went on to explain that this ancient occult knowledge had been carried to Rome and revealed to the Catholic Church and the popes, who desperately wanted to keep this arcane knowledge secret. In his essay, the chapter on Tarot meanings explains the detailed symbolism of Tarot artwork and connects it to the legends of Isis, Osiris and other Egyptian gods.
German-suited decks for Bauerntarock, Württemberg Tarock and Bavarian Tarock are different. They are not true tarot/tarock packs, but a Bavarian or Württemberg pattern of the standard German-suited decks with only 36 cards; the pip cards ranging from 6 to 10, Under Knave (Unter), Over Knave (Ober), King, and Ace. These use Ace-Ten ranking, like Klaverjas, where Ace is the highest followed by 10, King, Ober, Unter, then 9 to 6. The heart suit is the default trump suit. The Bavarian deck is also used to play Schafkopf by excluding the Sixes.
Scientists who study anomalistic psychology consider mediumship to be the result of fraud and psychological factors. Research from psychology for over a hundred years suggests that where there is not fraud, mediumship and Spiritualist practices can be explained by hypnotism, magical thinking and suggestion. Trance mediumship, which according to Spiritualists is caused by discarnate spirits speaking through the medium, can be explained by dissociative identity disorder.
Now that you are becoming a medium, you'll need a very active, highly attentive spirit guide who'll take on the task of being the gatekeeper for communication. They'll help to screen spirits coming to you for communication and aid spirits struggling to get their meaning across. The guides bring the spirits forward to you and align their vibrations with yours. They are a little like a customer adviser. They manage the line of customers and give them access to you and the client when it's their turn. You need to establish who this special spirit guide is, there may be more than one, and build relationships with them. Your vibration must be tuned with theirs on a deep and permanent level.
There are many varieties of Tarot decks, and there is no standard number of cards across all decks. While the types of cards, the suits and their meanings are the same, the illustrations vary greatly. Decks are based on various themes such as nature, animals, fantasy, dragons, etc. The most common deck in the United States is the Rider-Waite deck, which was created in 1909 by A.E. Waite, a prominent member of the aforementioned occult group The Hermetic Order of the Golden Dawn, and published by Rider & Company. The artist was Pamela Colman Smith. This 78-card deck was the only readily available deck in the United States for many years, which is why some consider it the "definitive" tarot deck in the U.S.
In contrast, the meanings in other decks are particularly difficult to decipher, like the infamous Thoth tarot developed by Aleister Crowley, notorious for his involvement with various cults and experimentation with recreational drugs and so-called “sex magick.” Completed in 1943, the Thoth deck was illustrated by Lady Frieda Harris and incorporated a range of occult and scientific symbols, inspiring many modern decks. As Wolf explains, “with the rise of the divination market in the 20th century, more liberties were taken, and the imagery evolved into increasingly personal artistic statements, both in content and style of execution.”
