The Book of Spirits - Allan Kardec

The time has come to know the truth, and Spiritism comes to elucidate important issues in an open way, without mistakes or symbolism. It does not require blind belief; on the contrary, it is enough to know why one believes for faith in God to be true, based on reason. By demonstrating the immortality of the soul, Spiritism revives faith in the future, showing us that this future can be good, depending only on ourselves. The Spirits' Book is the compilation of the teachings of this renewing doctrine, which makes us understand everything that previously seemed incomprehensible. This is a work that, more than a book to be read, is a manual of conduct for life.
