Heaven and Hell

In this book, Allan Kardec approaches divine justice from the point
of view of Spiritism. The first part is a comparative analysis of the
concepts of different faiths about heaven, purgatory and hell, angels
and demons, and future punishments and rewards. The dogma of
eternal punishments is specially discussed and refuted by arguments
taken from the laws of nature. The second part presents numerous
communications with spirits in different situations, and which shed
light on the state of the soul after death and its passage from the
physical life to the spirit life, which until then had been obscure and
feared. It is a sort of travel guide to be used before we enter into a
new world!
