I have created an Amazon Kindle and a paperback book which covers the basic principles of the Doctrine of Spiritism. I have set the lowest price available ($0.99) on Amazon Kindle so anyone should be able to download the book on their reader.
I wrote the book because when my wife and I first opened our Spiritual Center on Bainbridge Island, WA, I was amazed that people were interested in Spiritism, yet had absolutely no knowledge of it.
Here is the link to Spiritism 101 – The Third Revelation
Also, if you think it is useful, please leave a good review at Amazon, it will help to get the word out!
I also have this book in PDF format on the Facebook site – Spiritism and the Spirit World Around Us, in the files section.
