Sri K. Pattabhi Jois was an influential Indian yoga teacher, born in 1915, who popularized the Ashtanga Vinyasa Yoga system. He studied for 25 years under T. Krishnamacharya, eventually establishing the Ashtanga Yoga Research Institute in Mysore, India. Jois's dynamic, breath-synchronized practice, which links postures into a flowing sequence, has deeply influenced modern yoga, with his grandson, Sharath Rangaswamy, continuing his legacy.
