Yoga is a family of ancient spiritual practices that originated in India, where it remains a vibrant living tradition and is seen as a means to enlightenment. Karma Yoga, Bhakti Yoga, Jnana Yoga, and Raja Yoga are considered the four main yoga’s, but there are many other types. In other parts of the world where yoga is popular, notably the United States, yoga has become associated with the asanas (postures) of Hatha Yoga, which are popular as fitness exercises. Yoga as a means to enlightenment is central to Hinduism, Buddhism, Sikhism, and Jainism, and has influenced other religious and spiritual practices throughout the world. There is no Hinduism without Yoga and there is no Yoga without Hinduism.
