While this author titles his book demons and spirits, he admits that many of these are "attachments" which are likely other than demons... and may be just a fragment of someone's soul. If that sentence doesn't entice you, nothing will! It is an interesting book, worth reading by everyone in the psychic/mediumship business. However, although I found some valuable insights, I hope someone is going to write about this without the basis in Christianity. The author admits this is much older than Christianity, even the removal of such. He wants to quibble over the "right" way to remove them. I hope someone writes another book that includes other entities as well.
