The Dalai Lama turned 90 this week, but who is he really? Dr. Ruth Gamble gives us an insightful overview into the life and role of the Dalai Lama. We learn about his religious influence as a top Buddhist teacher, his political history as a leader of the Tibetan people, and his exile from Tibet in 1959. Dr. Gamble also explains the complex process for selecting a new Dalai Lama, the Chinese government's competing claim, and the likelihood of having two Dalai Lamas in the future.
