Drawing on hundreds of interviews with people who have had both near-death and mystical experiences, Berman explores the universal truths these moving stories reveal. As a student of comparative religions, he shows us the similarities that exist in these stories across time and cultures, similarities that allow us to define the enduring themes of these encounters. Berman argues that these experiences are the wellspring of all the world's great religions, and that their message of the oneness of creation and the Divine spark within us all, forms "an eternal theology".
