I noticed that some of the other reviewers reacted negatively to this book, and I think I know why. Having a seance is not an exact science. Different people do it different ways. The author left it open so that people would not think there was a specific set of rules that must be followed. For those analytical people (like myself), this can often be frustrating, yet I have found it to be true.
I have read several books regarding spiritual things, and this is by far the best. Many seem to be written by people who didn't graduate elementary school, but this author is knowledgeable, intelligent, and an excellent writer. I felt completely comfortable with his writing, and I learned many things that I did not already know.
The book is not a rulebook... I don't think one exists. But this book will give you an overall philosophy about seances and mediumship, and I have found everything in the book to agree with my own experiences with the spiritual world.
You won't be disappointed.
I was surprised to see that the other reviewers did not like this book. But we each have our perceptions, and they are always valid for each one of us.
I personally thought this was an excellent book. I thought the author did a wonderful job researching this topic. Because of what I learned in this book, I plan to pursue participating in seances at my local spiritualist church.
The author also demonstrates knowledge of very high spiritual principles.
I recommend this book to anyone who is serious about seances.
