Tantra Yoga

During the Medieval period, around 800-1000 C.E., Hatha Yoga and Tantra Yoga began to branch separately from their common trunk, whose roots extend back at least into the ancient Indus Valley Culture- which flourished along the Indus and (the now dry) Saraswati river basins, from c.2500 B.C.E. to c.1500 B.C.E.
