Under this title, the reader will find a compendium of fascinating explanations about the mysteries of life and death. V.M. Samael Aun Weor bequeaths an invaluable wisdom to mankind, such as knowing what we are, what is real within us and what is false, what is eternal and what is perishable, etc. Furthermore, he explains the reality that our soul, free from its ties with the body, will find when the Angel of Death comes to liberate it. With this work, the reader will be able to end with the ignorance that surrounds the mankind’s process of disincarnation, and with the terror that this entails for the humanoids who, far from the light of their Being, live identified with the things of life and in oblivion of that portion of eternity that we all carry within us.
