In old-line Spiritualism, a portion of the services, generally toward the end, is given over to demonstrations of mediumship through contact with the spirits of the dead. A typical example of this way of describing a mediumistic church service is found in the 1958 autobiography of C. Dorreen Phillips. She writes of the worship services at the Spiritualist Camp Chesterfield in Chesterfield, Indiana: "Services are held each afternoon, consisting of hymns, a lecture on philosophy, and demonstrations of mediumship."
It is claimed that the telepathic communications come from highly evolved spirit beings existing in the normally invisible realms of the spirit dimension. Sometimes the medium will have a vision in which he or she sees the spirit in a visible form, manifested in the imagination faculties of the medium’s consciousness. The spirit guides are said to sometimes wear white robes and often radiate brilliant, golden-white light. Channelers claim that the messages received represent divine wisdom and truth, and have beneficial value for mankind.
Here's what happened: The experienced psychographers showed lower levels of activity in the left hippocampus (limbic system), right superior temporal gyrus, and the frontal lobe regions of the brain during psychography compared to their normal (non-trance) writing. The frontal lobe areas are associated with reasoning, planning, generating language, movement, and problem solving, which means that the mediums were experiencing reduced focus, lessened self-awareness and fuzzy consciousness during psychography.
Even the greatest amount of spiritual reading would amount to a waste of time if it did not affect our souls. How do we make it stick in our spiritual life? First, we should keep Padre Pio’s advice: ask for the assistance of the Holy Spirit, and what God wants to communicate to us in that particular book. Another way to do this is by journaling. Writing down thoughts or insights helps us process new information, as well as helping us remember it. If it’s easier to type than write, one might try starting a blog. Anyone can do it, and there are many free sites available.
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.”
Magicians have a long history of exposing the fraudulent methods of mediumship. Early debunkers included Chung Ling Soo, Henry Evans and Julien Proskauer. Later magicians to reveal fraud were Joseph Dunninger, Harry Houdini and Joseph Rinn. Rose Mackenberg, a private investigator who worked with Houdini during the 1920s, was among the most prominent debunkers of psychic fraud during the mid-20th century.
