About Spiritism

It is the set of laws and principles, as revealed by the Superior Spirits, contained in the works of Allan Kardec, which constitute the Spiritist Codification: The Spirits' Book, The Mediums' Book, The Gospel According to Spiritism, Heaven and Hell, and The Genesis.
• "Spiritism is a science which deals with the nature, origin and destiny of Spirits, as well as their relationship with the corporeal world." Allan Kardec (Taken from Qu'est-ce que le Spiritisme? - Préambule) Translated from the original French.
• "Spiritism realises what Jesus said of the promised Consoler, by bringing knowledge of those things which allow Man to know where he came from, where he is going and why he is on Earth; so attracting mankind towards the true principles of God's law and offering consolation through faith and hope."
Allan Kardec (Taken from The Gospel According to Spiritism - Chap. 6 - Item 4, Translated from the original French)
