In the 1930s Harry Price (director of the National Laboratory of Psychical Research) had investigated the medium Helen Duncan and had her perform a number of test séances. She was suspected of swallowing cheesecloth which was then regurgitated as "ectoplasm". Price had proven through analysis of a sample of ectoplasm produced by Duncan, that it was made of cheesecloth. Helen Duncan would also use a doll made of a painted papier-mâché mask draped in an old sheet which she pretended to her sitters was a spirit. The photographs taken by Thomas Glendenning Hamilton in the 1930s of ectoplasm reveal the substance to be made of tissue paper and magazine cut-outs of people. The famous photograph taken by Hamilton of the medium Mary Ann Marshall depicts tissue paper with a cut out of Arthur Conan Doyle's head from a newspaper. Skeptics have suspected that Hamilton may have been behind the hoax.
Do your homework when choosing a medium either for teaching or for having a reading performed for yourself. You might want to attend a few readings before deciding to go ahead and practice mediumship yourself. How long have they been practicing? Do they come recommended? Do they belong to an online community where they are rated? Did they have any formal training? There are official organisations and colleges that train mediums if you care to research them, you could study at one yourself! Always thoroughly check and ask for recommendations before joining any group, teacher or organisation.
Second, when the spirit speaks to Saul and gives a prediction, the spirit says, "tomorrow you and your sons will be with me.” Again we have to ask, if Samuel is a good man and prophet of the Lord, isn't he supposed to be in heaven? If we assume that the spirit of Samuel is in heaven, then, how can Saul, who is in rebellion against the Lord, also end up where Samuel is the next day? It seems the spirit is a lying spirit!
The first thing you should know before going to a medium demonstration or private reading is that psychic mediums are basically a human telephone to the spirit world—they communicate with spirits. Unfortunately, they are a telephone without a dial. A psychic medium can’t just call up anyone from the spirit world with whom you want to talk. Instead, you get whoever is on the other end when the psychic medium “links” with the spirit world.
For example, you smell your grandmother’s perfume or your grandfather’s cigar when you are in your car or in your bedroom. At times, you may feel anxious when you walk into certain rooms and then feel better once you leave. Whatever the case may be, if there are ghosts that haven’t crossed over in your life, we will cross them into the light and help them continue on their journey.
Clairvoyance, where you see images, objects, people and scenes presented to you in your mind's eye. For this it's best to build up a bank of symbols (archetypes) for spirits to present to you that represent certain meanings to you. Your mind is an open book to the spirit world as long as you allow it. Your personal language of symbols and their meanings is accessible to them. As an example, if you decide that a horse represents freedom to you, if spirit shows you a horse then the topic is going along the lines of the client needing more freedom or gaining more freedom. Other accompanying symbols should clarify this.
Celtic Cross Tarot card reading predicts your future by reading the cards. This is different from prophesies using calculations of date, time and year of birth. Each prediction or card selection may not indicate the same result. The accuracy depends on your intention and concentration at the time of selection. Thus, it is very important to concentrate hard to achieve the most significant outcome.
