She asked for Emily's photo. I handed her my phone. She stared at the screen and told me to say Emily's full name and birthday, then looked up at me. My heart dropped—would my face betray something?—and immediately jumped back into my chest when she told me she could feel Emily's presence and that she was happy. In a new development, Emily had "passed on" and become my guardian angel.

The process is known as synchronicity, a term coined by psychologist Carl Jung to describe the temporally coincident occurrence of events. In synchronicity, there is no distinction between inner and outer. The choice of a card is exactly what your higher self already knows. This is what tarot occultists call the conversation with your higher self. The cards always work. It’s not magic—tarot cards are a sacred mirror.
Modern spiritualists and psychics keep detailed files on their victims. As might be expected, these files can be very valuable and are often passed on from one medium or psychic to another when one retires or dies. Even if a psychic doesn't use a private detective or have immediate access to driver's license records and such, there is still a very powerful technique that will allow the psychic to convince people that the psychic knows all about them, their problems, and their deep personal secrets, fears, and desires. The technique is called cold reading and is probably as old as charlatanism itself... If John Edward (or any of the other self-proclaimed speakers with the dead) really could communicate with the dead, it would be a trivial matter to prove it. All that would be necessary would be for him to contact any of the thousands of missing persons who are presumed dead—famous (e.g., Jimmy Hoffa, Judge Crater) or otherwise—and correctly report where the body is. Of course, this is never done. All we get, instead, are platitudes to the effect that Aunt Millie, who liked green plates, is happy on the other side.[192]

The psychical researchers Eric Dingwall and Harry Price re-published an anonymous work written by a former medium entitled Revelations of a Spirit Medium (1922) which exposed the tricks of mediumship and the fraudulent methods of producing "spirit hands".[132] Originally all the copies of the book were bought up by spiritualists and deliberately destroyed.[133] In 1923, the magician Carlos María de Heredia revealed how fake spirit hands could be made by using a rubber glove, paraffin and a jar of cold water.[134]
