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 first half of a two-part interview, Tami speaks with Dr. Hanson about the ways we can “install” positive brain states as lasting traits; how we can respond in situations when we feel our basic needs are threatened; and the three ways of working with unpleasant experiences—letting be, letting go, and letting in.
