Hi,
As a frequent visitor to spiritualist churches, i have come to the conclusion that about 90% of platform mediums are not very good. They may believe they are genuine but they fish for clues from the audience. Of the remaining 10% i think around 8% are quite good. They give information that only you would know. That leaves 2 out of 100 who i think are the real deal. They know things about you that they shouldn`t know.
Never expect too much from a visit to a spiritualist church. It may take 7 visits before you get a message yourself. The more you go, the more you will be able to seperate the good from the not so good but above all, enjoy the experience.
