Furthermore, she learned her trade from the mediums Frank Herne and Charles Williams, who were notorious for their cheating." Also see M. Lamar Keene. (1997). The Psychic Mafia. Prometheus Books. p. 64. ISBN 978-1-57392-161-9 "The most famous of materialization mediums, Florence Cook – though she managed to convince a scientist, Sir William Crookes, that she was genuine – was repeatedly exposed in fraud. Florence had been trained in the arts of the séance by Frank Herne, a well-known physical medium whose materializations were grabbed on more than one occasion and found to be the medium himself."
Even the earliest known tarot decks weren’t designed with mysticism in mind; they were actually meant for playing a game similar to modern-day bridge. Wealthy families in Italy commissioned expensive, artist-made decks known as “carte da trionfi” or “cards of triumph.” These cards were marked with suits of cups, swords, coins, and polo sticks (eventually changed to staves or wands), and courts consisting of a king and two male underlings. Tarot cards later incorporated queens, trumps (the wild cards unique to tarot), and the Fool to this system, for a complete deck that usually totaled 78 cards. Today, the suit cards are commonly called the Minor Arcana, while trump cards are known as the Major Arcana.
One time I did a sitting for a woman, and no one came through at all. I told her that it didn’t mean they didn’t love her, and maybe it just wasn’t the right time. We decided to try again in six months. When she came back, it transpired that in those months she’d lost someone quite close to her, and somehow those in the Spirit World held back in the last sitting because it was simply not the right time.
When you ask the Tarot cards a question on behalf of someone else (who has given permission for the reading and whose energy is invested in the reading), you are tapping into this collective wisdom. You are picking up all sorts of intuitive messages through the Tarot cards and through your connection with the collective wisdom. And those insights are channeled through you to the person you’re reading for, often in a very powerful way.
A widely known channeler of this variety is J. Z. Knight, who claims to channel the spirit of Ramtha, a 30 thousand-year-old man. Others purport to channel spirits from "future dimensions", ascended masters, or, in the case of the trance mediums of the Brahma Kumaris, God. Other notable channels are Jane Roberts for Seth, Esther Hicks for Abraham, and Carla L. Rueckert for Ra.
The article about this phenomenon in Encyclopædia Britannica places emphasis that "… one by one spiritual mediums were convicted of fraud, sometimes using the tricks borrowed from scenic "magicians" to convince their paranormal abilities". In the article it is also noted that "… the opening of the wide ranging fraud happening on spiritualistic sessions caused serious damage to reputation of the movement of a Spiritualism and in the USA pushed it on the public periphery".
