Modern yoga is a wide range of yoga practices with differing purposes, encompassing in its various forms yoga philosophy derived from the Vedas, physical postures derived from Hatha yoga, devotional and tantra-based practices, and Hindu nation-building approaches.
The scholar Elizabeth de Michelis proposed a 4-part typology of modern yoga in 2004, separating modern psychosomatic, denominational, postural, and meditational yogas. Other scholars have noted that her work stimulated research into the history, sociology, and anthropology of modern yoga, but have not all accepted her typology. They have variously emphasised modern yoga's international nature with its intercultural exchanges; its variety of beliefs and practices; its degree of continuity with older traditions, such as ancient Indian philosophy and medieval Hatha yoga; its relationship to Hinduism; its claims to provide health and fitness; and its tensions between the physical and the spiritual, or between the esoteric and the scientific.
Early modern yoga
In the early years of British colonialism in India, the elites from the United States, Europe, and India rejected the concept of hatha yoga and perceived it as unsociable. By the late 19th century, yoga was presented to the Western world in different forms such as by Vivekananda and Madame Blavatsky. It embodied the period's distaste for yoga postures and hatha yoga more generally, as practised by the despised Nath yogins, by not mentioning them. Blavatsky helped to pave the way for the spread of yoga in the West by encouraging interest in occult and esoteric doctrines and a vision of the "mystical East". She had travelled to India in 1852-3, and became greatly interested in yoga in general, while despising and distrusting hatha yoga. In the 1890s, Vivekananda taught a mixture of yoga breathwork (pranayama), meditation, and positive thinking, derived from the new thought movement, again explicitly rejecting the practice of asanas and hatha yoga.
