Dharma means, variously, “path,” “teaching,” or “law.” For our purposes in this book it will mean primarily “vocation,” or “sacred duty.” It means, most of all—and in all cases—truth. Yogis believe that our greatest responsibility in life is to this inner possibility—this dharma—and they believe that every human being’s duty is to utterly, fully, and completely embody his own idiosyncratic dharma.
