You are not just a radio. You can't simply tune yourself in and receive the signal, although this analogy isn't far from the truth. Some spirits in the spirit realm find it easier to initiate and maintain contact than others. Some find it easier to communicate understandably than others. It's like working in a busy store, some of your spirit customers will be easy to deal with, some tricky. You may need to almost counsel a spirit through contact if their energy is weak, if it's a faint connection or if they're experiencing any other difficulty. Again this is all learned through experience.
In English-speaking countries, where these games are not played, tarot cards are used primarily for divinatory purposes, usually using specially designed packs. The cards are traced by some occult writers to ancient Egypt or the Kabbalah but there is no documented evidence of such origins or of the usage of tarot for divination before the 18th century.
In 1918, Joseph Jastrow wrote about the tricks of Eusapia Palladino who was an expert at freeing her hands and feet from the control in the séance room. In the séance room Palladino would move curtains from a distance by releasing a jet of air from a rubber bulb that she had in her hand. According to the psychical researcher Harry Price "Her tricks were usually childish: long hairs attached to small objects in order to produce 'telekinetic movements'; the gradual substitution of one hand for two when being controlled by sitters; the production of 'phenomena' with a foot which had been surreptitiously removed from its shoe and so on."
For the less experienced mediums, exactly the opposite was observed--increased levels of activity in the same frontal areas during psychography compared to normal writing, and the difference was significant compared to the experienced mediums. What this probably means is that the less experienced mediums were trying really hard. The force is not yet strong with them.
The trance medium Leonora Piper was investigated by psychical researchers and psychologists in the late 19th and early 20th century. In an experiment to test if Piper's "spirit" controls were purely fictitious the psychologist G. Stanley Hall invented a niece called Bessie Beals and asked Piper's 'control' to get in touch with it. Bessie appeared, answered questions and accepted Hall as her uncle. The psychologist Joseph Jastrow wrote that Piper pretended to be controlled by spirits and fell into simple and logical traps from her comments. Science writer Martin Gardner concluded Piper was a cold reader that would "fish" for information from her séance sitters. The physiologist Ivor Lloyd Tuckett who examined Piper's mediumship in detail wrote it could be explained by "muscle-reading, fishing, guessing, hints obtained in the sitting, knowledge surreptitiously obtained, knowledge acquired in the interval between sittings and lastly, facts already within Mrs. Piper's knowledge."
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".
But to balance such arcane decks, there are divinatory cards that offer little room for interpretation, like “Le Scarabée d’Or” or The Golden Beetle Oracle, one of Wolf’s most prized decks. “It’s just fantastically bizarre. There’s a little window in the lid of the card box, and when you shake it, the beetle appears, and points to a number,” he explains. “Then you find the corresponding number on a set of round cards, with beautiful script text on them, and read your fortune. Can you not imagine standing in a Victorian parlor in France, consulting the Golden Beetle? It was like performance art.”
The illustrations of French-suited tarot trumps depart considerably from the older Italian-suited design, abandoning the Renaissance allegorical motifs. With the exception of novelty decks, French-suited tarot cards are almost exclusively used for card games. The first generation of French-suited tarots depicted scenes of animals on the trumps and were thus called "Tiertarock" ('Tier' being German for 'animal') appeared around 1740. Around 1800, a greater variety of decks were produced, mostly with genre art or veduta. Current French-suited tarot decks come in these patterns:
Another important distinction is that while psychic readings often focus on predicting future events, mediums primarily tune into past and present issues. It's my opinion that predicting the future, while sometimes helpful, runs the risk of disempowering people. Always remember that you do have a say in how your future unfolds. Despite what any psychic or medium may "see" in your future, it is important to remember you were given the gift of free will when you came into this world, and at any moment in time you can absolutely redirect your course and create the life you want by changing your thoughts and actions. Psychic information is often just insight into what potentially could happen based on the road you are currently traveling—and it should be used only as a guideline to help you make the best choices for yourself.
There are many ways of working with the deck. You should choose your own deck by being drawn to it intuitively. There are layers upon layers of systems to learn, including Kabbalah, the tree of life, colour scales, Hebrew letters, numerology, pathways, symbolism, alchemy, astrology, mythology and learning to meditate with each card directly. The more layers you learn the deeper your knowledge and insight into the cards.
