Can the power of the mind help humans self-heal? That’s what a group of scientists are hoping to help determine by studying a Tibetan lama who believes he cured himself of gangrene through meditation. When Tibetan Lama Phakyab Rinpoche immigrated to the United States in 2003, he was a 37-year-old refugee with diabetes and Pott’s Disease. His afflictions had gotten so bad that his right foot and leg had developed gangrene. He was hospitalized and examined by three different doctors in New York City who all gave the same treatment recommendation: amputate.
