Victor Zammit has a fascinating piece on materializations on his website : Some of you would know that my partner Wendy and I, who are both professionally qualified in Scientific Method and Psychology, have been attending and investigating David Thompson's materializations for almost five years now. We need to remember that it was materializations which convinced some of the greatest scientists this world has ever seen of the existence of the afterlife. I can tell you from personal experience that even if you believe in the afterlife nothing can prepare you for the reality of that first experience of materialization. On more than seventy occasions we have seen guests to the circle speaking directly with and touching their loved ones from the spirit world.
