''Without wanting to hurt delicate susceptibilities in any way, we must emphasize the basic idea that a variety of venerable institutions coexist within the cultural-spiritual environment of contemporary humanity that very sincerely believe they know the Secret Path. Nonetheless, they do not know it. ''In all the books of ancient times, the Secret Path is cited. This Path is quoted and mentioned in many verses; yet people do not know it. ''Beloved reader, to unveil, to show and to teach the esoteric path that leads to the Final Liberation is certainly the purpose of this book that you have in your hands. This is one of the books of the Fifth Gospel. ''The great German initiate Goethe wrote, ''Every theory is gray and only the tree of the golden fruits of life is green.'' ''Certainly, what we deliver in this new book are transcendental lived experiences. It is what we have verified, what we have directly experienced.'' For the first time in the history of humanity, the path of Initiation has been explained from beginning to end. This is not a collection of references from various spiritual treatises: this is the direct experience of the author. In this work Samael Aun Weor explains the essential outline of the Direct Path to the realization of the Being. The Direct Path is the only way to reach the heights of spiritual development, and was indicated with precision by Jesus of Nazareth: ''Enter by the narrow gate; for the gate is wide and the way is easy that leads to destruction, and those who enter by it are many. For the gate is narrow and the way is hard that leads to life, and those who find it are few.'' - Matthew 7:13
