A typical example of this way of describing a mediumistic church service is found in the 1958 autobiography of C. Dorreen Phillips. She writes of the worship services at the Spiritualist Camp Chesterfield in Chesterfield, Indiana: "Services are held each afternoon, consisting of hymns, a lecture on philosophy, and demonstrations of mediumship."
I thought i would mention that all Psychic related abilities are GIFTS that some of us receive, not everyone who claims to be gifted is genuine and 100%.

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.
