The Fallen Goddess Scenario is not the invention of John Lamb Lash---it is his reconstruction of a mythic narrative developed by Ancient Gnostic Seers, intellectual shamans of the Pagan Mysteries, who applied it as a vision story for guiding humanity to evolve interactively with the living planet, Gaia/Sophia. The Nag Hammadi Codices were found by chance in Egypt in 1948, making them the earliest examples that survive of bound books with numbered pages.
This is the most suppressed story for a reason: it is the most empowering narrative that tells the biography of the earth itself. This is the story of our galactic beginnings before the earth or humanity existed. As a animistic myth, it attributes the equivalent of emotion, ideation and intention to the Cosmic Energies of the galaxy imaginatively realized as gods and goddesses. This is a story that can be known directly which leaves the future open and in need of human imagination and interaction to solve it's problems.
