Tami Simon speaks with Dr. Rick Hanson, a neuropsychologist and the founder of the Wellspring Institute for Neuroscience and Contemplative Wisdom. He is the author of the books Buddha’s Brain and Hardwiring Happiness, and with Sounds True has created several audio programs, including The Enlightened Brain and the new learning course Self-Directed Brain Change. In the second half of a two-part interview, Tami speaks with Dr. Hanson about how we can move from a “red” reactive state to a “green” state of calm, how this progression aligns with the Four Noble Truths of Buddhism, and his vision for how healthy brains can change the state of our world.
