The researchers speculate that maybe as frontal lobe activity decreases, "the areas of the brain that support mediumistic writing are further disinhibited (similar to alcohol or drug use) so that the overall complexity can increase." In a similar manner, they say, improvisational music performance is associated with lower levels of frontal lobe activity which allows for more creative activity.
The biblical basis of this practice is St. Paul's advice to his disciple Timothy whom he appointed bishop. St. Paul told him to "Attend to reading." The word "attend" an allusion to the many other concerns that a bishop has to attend to. By this, according to St. Alphonsus Liguori, Doctor of the Church on Moral theology, the Apostle Paul "wished him to apply to the reading of holy books, not in a passing way and for a short time, but regularly and for a considerable time."
The physicist Kristian Birkeland exposed the fraud of the direct voice medium Etta Wriedt. Birkeland turned on the lights during a séance, snatched her trumpets and discovered that the "spirit" noises were caused by chemical explosions induced by potassium and water and in other cases by lycopodium powder. The British medium Isa Northage claimed to materialize the spirit of a surgeon known as Dr. Reynolds. When photographs taken of Reynolds were analyzed by researchers they discovered that Northage looked like Reynolds with a glued stage beard.
Like common playing cards, the tarot has four suits (which vary by region: French suits in Northern Europe, Latin suits in Southern Europe, and German suits in Central Europe). Each suit has 14 cards, ten pip cards numbering from one (or Ace) to ten and four face cards (King, Queen, Knight, and Jack/Knave). In addition, the tarot has a separate 21-card trump suit and a single card known as the Fool. Depending on the game, the Fool may act as the top trump or may be played to avoid following suit. These tarot cards, without occult symbology, are still used throughout much of Europe to play card games.
