In ancient times, the Gnostics sought for salvation through personal, experiential knowledge of the Divine. Their methods of self-reliance and their sublime knowledge profoundly impacted society, such that the dominant powers felt threatened and the tradition was forced to disappear from public view. Now, after centuries of obscurity, the Gnostics have re-emerged, still carrying their profound message of Gnosis: knowledge of self and the Divine. In a simple and elegant way, Samael Aun Weor explains the basic methodology for people in todays world to begin to approach the greater mysteries of the Gnostics. In this basic and practical guide, Samael Aun Weor offers a breadth of exercises guiding the reader to discover within themselves a wealth of insight and understanding. Gnosis, after all, is Greek for knowledge, and the seeker is told, Know thyself, and thou shalt know the universe and its Gods.
