A fact supported by the suppressed Gnostic Gospel of Philip: "Those who say they will die first and then rise are in error. If they do not first receive the resurrection while they live, when they die they will receive nothing." He reveals how these practices were not only common in the ancient world but also shared similar facets in each tradition: initiates were led through a series of challenging ordeals, retreated for a three-day period into a cave or restricted room, often called a "bridal chamber," and while out-of-body, became fully conscious of travels in the Otherworld. Upon returning to the body, they were led by priests or priestesses to witness the rising of Sirius or the Equinox sunrise.

Silva describes some of the secret chambers around the world where the ritual was performed, including the so-called tomb of Thutmosis III in Egypt, which featured an empty sarcophagus and detailed instructions for the living on how to enter the Otherworld and return alive.

He reveals why esoteric and Gnostic sects claimed that the literal resurrection of Jesus promoted by the Church was a fraud and how the Church branded all living resurrection practices as a heresy, relentlessly persecuting the Gnostics to suppress knowledge of this self-empowering experience. He shows how the Knights Templar revived these concepts and how they survive to this day within Freemasonry.
