More authors dealing with Law of Attraction: all the writers in association with Unity Church. Emmett Fox and Catherine Ponder come to mind, in particular. I'll have to check if Ernest Holmes is tied to Unity, but I'm sure his books are on their reading list. Marianne Williamson as well...
There was only one difference between Unity Church and the Spiritualist Church/Organization : the spiritualists dealt with paranormal phenomenon, but the metaphysical philosophy was the same as Unity's. Unity simply doesn't focus on afterlife/psychic phenomenon -- but they do do "magic", even if they don't call it such.
Catherine PonderIf one one can suspend the distraction of anecdotal material from The Bible, there is some worthwhile material here. I still have several of her books ... Dynamic Laws of Healing, Dynamic Laws of Prayer, Dynamic Laws of Prosperity, and Healing Secrets of the Ages. The rest of her books are really redundant from these 4, based on my scannings. In "Healing Secrets", one must think in terms of "6 chakras", not 7.
Again, offered for interest's sake.
