In this basic and practical introduction to the fundamental basis of Gnosis, Samael Aun Weor offers a breadth of exercises for the reader to establish stability and understanding in their daily life. The sincere person who implements the guidance given in this profound book will discover a wealth of insight from their efforts. Gnosis is, after all, "knowledge" (Greek) and each seeker is enjoined to "Know Thyself." This volume, although simple in its expression and thin in size, exudes the perfume of many centuries of profound Initiatic Wisdom. Includes the lecture "How to Make Light Within" and the pamphlet "Marriage, Divorce, and Tantrism."
