Playing cards first entered Europe in the late 14th century, most likely from Mamluk Egypt, with suits of Batons or Polo sticks (commonly known as Wands by those practicing occult or divinatory tarot), Coins (commonly known as disks, or pentacles in occult or divinatory tarot), Swords, and Cups. These suits were very similar to modern tarot divination decks and are still used in traditional Italian, Spanish and Portuguese playing card decks.
The biblical basis is St. Paul's advice "Attend to reading" (1 Tim 4:13) which meant that Timothy his disciple should "apply to the reading of holy books, not in a passing way and for a short time, but regularly and for a considerable time," said St. Alphonsus Liguori, Doctor of the Catholic Church on Moral theology. St. Bernard of Clairvaux said that "spiritual reading and prayer are the arms by which hell is conquered and paradise won."
Spiritualists believe that phenomena produced by mediums (both mental and physical mediumship) are the result of external spirit agencies. The psychical researcher Thomson Jay Hudson in The Law of Psychic Phenomena (1892) and Théodore Flournoy in his book Spiritism and Psychology (1911) wrote that all kinds of mediumship could be explained by suggestion and telepathy from the medium and that there was no evidence for the spirit hypothesis. The idea of mediumship being explained by telepathy was later merged into the "super-ESP" hypothesis of mediumship which is currently advocated by some parapsychologists.
Clairsentience occurs as a sense of knowing. It's similar to the psychic ability known as telepathy, except telepathy is performed between humans. Telepathy and clairsentience is the communication of a concept or idea as a whole, or a sense of knowing. It's the 'I feel like' of spirit communication. For example, the medium is not shown or told that uncle Fred was a successful businessman, she simply knows it all of a sudden. Furthermore, the medium may have the feeling of being a very successful person, and therefore knows that while we are on the topic of uncle Fred, he must have either been a successful man himself or is recognizing the success of your client. Accompanying information can clarify this.
Cold reading also explains why psychics have consistently failed scientific tests of their powers. By isolating them from their clients, psychics are unable to pick up information from the way those clients dress or behave. By presenting all of the volunteers involved in the test with all of the readings, they are prevented from attributing meaning to their own reading, and therefore can't identify it from readings made for others. As a result, the type of highly successful hit rate that psychics enjoy on a daily basis comes crashing down and the truth emerges – their success depends on a fascinating application of psychology and not the existence of paranormal abilities.
In 1930 the Polish medium Stanisława P. was tested at the Institut Metapsychique in Paris. French psychical researcher Eugéne Osty suspected in the séance that Stanislawa had freed her hand from control. Secret flashlight photographs that were taken revealed that her hand was free and she had moved objects on the séance table. It was claimed by spiritualists that during a series of séances in 1930 the medium Eileen J. Garrett channeled secret information from the spirit of the Lieutenant Herbert Carmichael Irwin who had died in the R101 crash a few days before the séance. Researcher Melvin Harris who studied the case wrote that the information described in Garrett's séances were "either commonplace, easily absorbed bits and pieces, or plain gobblede-gook. The so-called secret information just doesn't exist."
