Lithomancy readings usually involve especially suitable gems or stones that are immersed in water, or tossed as a set and read by mutual proximity. Its origins are unknown, and there are numerous different methodologies used by various cultures throughout the world. A recently more common variant is crystallomancy also known as crystal gazing. Using quartz as a crystal ball it is stereotypically depicted as gypsy fortune telling.
Just as in any profession, mediums have specialties and areas of expertise. Unlike Allison Dubois in Medium, I don't work with the police in solving crimes. Or, unlike Melinda Gordon in The Ghost Whisperer, I don't help tormented souls cross over. Over the years, it has become very clear that my job lies in working with souls who have happily crossed over to the other side and, for the most part, are at peace. Sure, they may have regrets or unresolved issues, but they're not haunted or lost. Oftentimes, it's the living that are not at peace. The main goal of your deceased loved ones and spirit guides is to assist you in moving on, free of grief and struggle, so you can fulfill your life lessons and enjoy your time here on earth.
For example, if a spirit wants to give the psychic medium the name Sandy, they might flash (in the psychic medium’s mind) the face of a person whom the psychic medium knows named Sandy. If they want to get the psychic medium to say the word “coffee,” they might show the psychic medium someone’s cat that had the name Coffee. This can be confusing and requires that the psychic medium interpret what they are seeing in their mind. For instance, the psychic medium might say cat rather than coffee; and to the person being read, the psychic medium might appear wrong when the psychic medium is actually just “misinterpreting” the message.
In September 1878 the British medium Charles Williams and his fellow-medium at the time, A. Rita, were detected in trickery at Amsterdam. During the séance a materialized spirit was seized and found to be Rita and a bottle of phosphorus oil, muslin and a false beard were found amongst the two mediums. In 1882 C. E. Wood was exposed in a séance in Peterborough. Her Indian spirit control "Pocka" was found to be the medium on her knees, covered in muslin.
