When we try to discover from the effects what the causes might be, reincarnation becomes an absolute necessity, an inherent part of humanity, in a word: a Law of Nature, By its very results it becomes evident in a material manner, so to speak, in the same way that a hidden motor reveals itself by its movement, It is the only way Man can find out where he came from, where he is going and why he is here on Earth and still be able to justify the many abnormalities and all the apparent injustices which present themselves during life. *
Without the principle of the pre-existence of the soul and the plurality of existences, the maxims of the Gospel in the most part become unintelligible, which is the reason why they have given rise to so many contradictory interpretations, This is the only principle which will restore them to their true and original meaning.
* See THE SPIRITS' BOOK, chapters 4 & 5; WHAT IS SPIRITISM, chapter 2, by Allan Kardec and also LA PLURALITÉ DES EXISTENCES by Pezzani, for further information on reincarnation.
