If yoga were to have a family dynasty—its own version of the Nehrus—it would be here, with the line formed by T. Krishnamacharya, his son TKV Desikachar, and his grandson, Kausthub Desikachar. In fact, it all flows from Krishnamacharya, who revived the ancient art in the early 20th century and spread the word through his disciples (who form three of the four main pillars of modern yoga): his son TKV (holistic yoga), his brother-in-law B. K. S. Iyengar (Iyengar yoga), and Sri K. Pattabhi Jois (Ashtanga yoga). Photographed in Madras, India.
