In this revolutionary work we find a new comprehensive approach to understanding our true nature and that of the world around us. It speaks to the constant need to investigate the world around us (science), to make sense of our findings (philosophy), and to apply them to our day-to-day living so as to improve ourselves and the world around us (ethics/religion). This approach is often referred to as the triple-aspect of Spiritism: the conjoining of Science, Philosophy, and Religion. Thus, “The Spirits’ Book” present us with both the foundations of Spiritism as well as a great place from which to start or deepen our personal search for meaning and purpose.
