Today "demonstration of mediumship" is part of the church service at all churches affiliated with the National Spiritualist Association of Churches (NSAC) and the Spiritualists' National Union (SNU). Demonstration links to NSAC's Declaration of Principal #9. "We affirm that the precepts of Prophecy and Healing are Divine attributes proven through Mediumship."
The tarot can be used for many different purposes. The archetypal images on the cards reflect your story back to you, helping you to better understand a specific moment in time, and your greater journey through life. Those same images make good meditation companions or can provide you with a ‘thought for the day.’ There is no limit to how these images can be used.
My sister and I both realized our gifts and then discovered from speaking with our father that his father's brother was an acknowledged psychic in Rome, Italy. And then I also realized I could read hands and what I would see would surprise everyone and what I would predict would happen. I was really surprised at what I was able to read off the hands of my friends.
Before any reading, be sure to shuffle (or "clear") the deck. This deliberate gesture should become a meditation. Feel the physicality of the cards in your hand, visualizing your question. If you're reading for another person, use this reflective moment to get to the root of their situation and help you formulate specific queries for them. Take as long as you need. Clearing the deck is a critical first step in reading tarot cards, as it opens the pathway between spiritual dimensions. Whenever you're ready, cut the cards into three and reorder the pile, face down. On your favorite cloth (be precious with your tarot deck), prepare to pull cards for your tarot "spread."
When you ask the Tarot cards a question on behalf of someone else (who has given permission for the reading and whose energy is invested in the reading), you are tapping into this collective wisdom. You are picking up all sorts of intuitive messages through the Tarot cards and through your connection with the collective wisdom. And those insights are channeled through you to the person you’re reading for, often in a very powerful way.
