1. Any of dozens of religious and quasireligious systems and methods, many of which are health-related. The word “yoga” comes from a Sanskrit term that literally means “yoke” and, in Hinduism, implies harnessing oneself to God. But, contextually or with a qualifier (e.g., “chakra,” “Chinese,” “Polarity,” “Taoist,” or “Tibetan”), the word “yoga” often seems to mean simply “religious or quasireligious practice or group of practices.” 2. A regimen of breath control, meditation, and stretching and strengthening exercises that is thought to promote mental, physical, and spiritual well-being.
