Yoga is a group of physical, mental, and spiritual practices or disciplines that originated in ancient India, aimed at controlling ('yoking') and stilling the mind, and recognizing the detached 'witness-consciousness' as untouched by the activities of the mind (Citta) and mundane suffering (Duḥkha). There are a broad variety of the schools of yoga, practices, and goals in Hinduism, Buddhism, and Jainism, and traditional forms and modern methods of yoga are practiced worldwide.
