Todd is joined this week by author and researcher Gary David.

David  has been intrigued by the American Southwest since his initial trip there in 1987. The following year he lived for about six months in northern New Mexico, where he studied archaeological ruins and rock art. In 1994 he moved to Arizona and began an intensive study of the ancestral Pueblo People (sometimes incorrectly referred to as the Anasazi) and their descendants the Hopi.

In 2006 after more than a decade of fieldwork and scholarly inquiry, his nonfiction book The Orion Zone: Ancient Star Cites of the American Southwest was published.

Todd is joined on the show by authors Dennis, Matt and Sheila Linn. Near-death experiences (NDEs) are common, well-documented, and similar across cultures throughout the world. Current estimates are that between 4 and 15 percent of the world's population have had an NDE. Some of the fascination with NDEs comes from the fact that they often result in great leaps in personal growth. These leaps are characterized by the loss of the fear of death, the healing of deep hurts, an increase in self-esteem and compassion for others, a sense of union with all things, and a clearer sense of how to fulfill one's purpose in life.

Author Miguel Connor joins Todd to talk about his latest book, "Voices of Gnosticism.  For several years,  Conner has engaged the most prominent writers and scholars on Gnosticism and early Christianity. These interviews with 13 leading scholars represent one of the best ways to get to know ancient Gnosticism, the movement that has inspired Dan Brown, Philip Pullman, Philip K. Dick and The Matrix movies.
