I have been fortunate enough to work with trance mediums, one especially gifted one, in a therapeutic context for several years now. I personally feel we truly know next to nothing about the mechanisms behind trance channeling and mediumship. Like Edison said, "We don't know one millionth of one percent about anything." I do think it's far more likely to be an integrative both/and rather than either/or pheonomenon with respect to subconscious production vs spirit speakers (to say nothing of tapping the collective unconscious) and that's about all I feel reasonably sure of. Quantum (Unified Field)theories/New Paradigm Science and the like holds promise as far as cracking the code on the the entire spectrum of super-normal phenomena. The study here sounds rudimentary. I would suggest interested readers see the research being done at Windbridge Institue, the Rhine Research Center, and IONS.
St. Edith Stein, Patron of Europe, converted to Catholicism after reading the autobiography of St. Teresa of Ávila on a holiday in Göttingen in 1921, at the age of 29. One evening Edith picked up an autobiography of St. Teresa of Ávila and read this book all night. "When I had finished the book, I said to myself: This is the truth." She went out the next day to buy a missal and a copy of the Catholic catechism.
Despite numerous instances of chicanery, the appeal of spiritualism was strong. Prominent in the ranks of its adherents were those grieving the death of a loved one. Many families during the time of the American Civil War had seen their men go off and never return, and images of the battlefield, produced through the new medium of photography, demonstrated that their loved ones had not only died in overwhelmingly huge numbers, but horribly as well. One well known case is that of Mary Todd Lincoln who, grieving the loss of her son, organized séances in the White House which were attended by her husband, President Abraham Lincoln. The surge of spiritualism during this time, and later during World War I, was a direct response to those massive battlefield casualties.
Spiritualists reacted with an uncertainty to the theories of evolution in the late 19th and early 20th century. Broadly speaking the concept of evolution fitted the spiritualist thought of the progressive development of humanity. At the same time however, the belief in the animal origins of humanity threatened the foundation of the immortality of the spirit, for if humans had not been created by God, it was scarcely plausible that they would be specially endowed with spirits. This led to spiritualists embracing spiritual evolution.
Do compose your emotions and appearance to hide any revealing information about yourself. Your facial expression, style of dress, personal mannerisms, and emotional outbursts can tell a psychic, especially a false one, a great deal about you to make it look like she knows all these things from a paranormal reading, when in fact, she is merely interpreting your physical appearance or reactions.
