I agree with dawkins, there are no powers except in the mind of the practicionar.Years ago I had an intense interest in all things mystical/supernatural.I was a member of a paranormal research group,played with ouja boards,visited countless mediums,practiced magic and spells,I had friends that were wiches (and for good measure, one that was a satanist)I practiced various forms of divination and tried astral projection and attended seances.I read literally hundreds of books over several years and even placed adds in magazines such as Prediction in an attempt to meet people who profesed to have any kind of occult power.I found absolutely nothing that couldnt be explained by rational means.Nowadays when I hear of yet another so called unexplained event i just sit and yawn.There are NO magic powers in the universe.
