This is the first Chinese translation of "The Spirits' Book," the foundational work of Spiritism, originally published by Allan Kardec in 1857, in Paris (original title "Le Livre des Esprits"). Spiritism includes over 15 million adherents worldwide, ahead of more historically traditional religions such as Judaism and Jainism. This is the first book one should read if interested in getting to know about Spiritism in general.
