A lifelong student of world mythology and the pre-Christian Mysteries, John Lash discussed the ancient Gnostic texts known as the Nag Hammadi, as well as the Gaia Hypothesis, Archons, origins, and calendars. In studying ancient cultures such as those of Egypt, he realized their astronomical and building knowledge stemmed from inner resources rather than technology, and many of their myths were based around an interface between the sky and the human mind.
