Tami Simon speaks with Richard Miller, a master of yoga and meditation who holds a doctorate in clinical psychology. He is recognized as a leading authority on the practice of yoga nidra, and is currently teaching iRest, a healing technique he developed based on deep relaxation and meditative inquiry. Richard has worked with Sounds True to create an integrated book-and-audio learning program called Yoga Nidra. Richard discusses the stages of yoga nidra, how the practice is a path to realization and self-inquiry, the nature of paradoxical sleep, and his ongoing work with soldiers suffering from post-traumatic stress disorder through the practice of yoga nidra.
