In this conversation, Christopher Key Chapple explores the wisdom at the heart of classical yoga — not the postures of modern practice but the ethical and philosophical path Patanjali charts in the Yoga Sutra. He speaks to the yamas of nonviolence and truthfulness, the doctrine of karma, and the Jain and Buddhist origins that shape yoga’s vision of liberation. A leading scholar of Indian religions and ecology, he reflects on how disciplined, compassionate living becomes a path to inner freedom, and on what this ancient wisdom offers a modern world.
