If you've decided to hire the services of a medium, for whatever reasons, there are a few things you should keep in mind in order to guarantee you get the best session possible. First of all, try to come in with an open mind. You may be feeling skeptical, but if you let that be an issue, it can certainly color your results. A corollary to that is that it's important to be honest about why you're there. If you're only trying to debunk things, or to expose the medium as a fraud, go ahead and admit it up front. A medium who's legitimate will probably still be willing to work with you.
The VERITAS Research Program of the Laboratory for Advances in Consciousness and Health in the Department of Psychology at the University of Arizona, run by the parapsychologist Gary Schwartz, was created primarily to test the hypothesis that the consciousness (or identity) of a person survives physical death. Schwartz claimed his experiments were indicative of survival, but do not yet provide conclusive proof. The experiments described by Schwartz have received criticism from the scientific community for being inadequately designed and using poor controls.
By comparing various decks from different time periods, tarot-card enthusiasts can identify the evolution of certain illustrations. “For example,” says Matthews, “the modern version of the hermit with the lantern, you’ll find that that was an hourglass and he was Saturn or Chronos, the keeper of time. You can see how that translates with the Tarot Bolognese meaning of delay or blockage. It was about time moving slowly, though that’s not used as a modern meaning much now.”
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.
