What happens after death? Is it the end of the road or the start of a different expression of life? Léon Denis answers these questions and many more, using plain and clear language. This book is an exposition on the Doctrine of the Spirits, a scientific and rational solution to the problems of life and death. It addresses the nature of the human being and sheds light on subjects such as the afterlife, spirits, heaven and hell, the invisible worlds, and all facets of the human soul. It discusses the will, judgment, the superior life, the cycles of reincarnation, immortality, God and much more. It is meant for those who are tired of living blind, who may not really know who they are or why they are here; those who are no longer satisfied with today’s materialistic civilization; those who aspire to a higher order of things.
