If it appears that the communication with people from the other side is as old mankind, "automatic writing" remains one of the most used ways to  match this "beyond".

The phenomenon or "direct writing, automatix writing" remained one of the most exciting in the world of parapsychology and paranormal and has been since its development by the French "Hippolyte Léon Rivail (aka Allan Kardec- 1804/1869)" from 1855 and enacted in outline in the first 500 page book "The book of Spirits- 1857".

Some authors consider today that "Spritualism" is the fourth largest religion revealed after the "Judaism, Christianity and Islam".
