A Concise History of Hatha Yoga
Although many forms of yoga training have existed for thousands of years, Hatha (the yoga of physical mastery) is a relative newcomer in comparison to the other main systems of Yogic methodology in India. Hatha dates back as recently as the 15th century with Svami Svatmarama and is the base for many popular styles today such as Iyengar, Bikram, Kundalini, and Ashtanga.
