Spiritism in its simplest expression (O espiritismo na sua expressão mais simples - inglês):

Wanting to popularize Spiritism and make spreading it easier and quicker, but without prejudicing the basic works of the Spiritist Doctrine, Allan Kardec wrote a number of booklets and distributed them throughout France at prices that were affordable for anyone who might be interested. Some of them had several printings and were highly successful. They continued to be republished even after the Codifier’s discarnation. This is one of those booklets. It is hoped that Spiritist readers will find that this unpretentious work enriches their knowledge of the Spiritist Doctrine.
