Mingyur Rinpoche, the author of "The Joy of Living: Unlocking the Secret and Science of Happiness," is a study of contradictions. On one hand, he's been formally recognized as the reincarnation of two Tibetan meditation masters. On the other hand, he has been working with scientists to design research around the impact meditation can have on the brain. In fact, he and other practitioners had their brain activity measured while meditating on compassion and the researchers were stunned by the results. Mingyur also freely admits that he suffered from anxiety and panic attacks as a child, and talks about how he turned to meditation for help.
