Perhaps the most intimate and metaphysical of Leon Denis’s many books, THE BIG ENIGMA often reaches the sublime in unforgettable passages that definitely do not seem to come from this world. Deeply moving and quite formidable thoughts succeed one another in endless continuity, leaving the reader in awe before the author’s complete certainty and conviction. There is a ring of sterling truth in all these philosophical and spiritual teachings from a brilliant thinker who has matured over the years during his long and difficult life. This is an inspired book that can nurture one’s mind and soul with genuine greatness and knowledge - and a life changer to many readers. Denis pays tribute to his Celtic and Gallic ancestors, letting his text flow with abandon, and showing that perhaps the biggest enigma of all was himself, as a thinker and writer, in the light of Spiritism.
