"Born Bellur Krishnamachar Sundararaja Iyengar in Karnataka’s Kolar district in 1918 and debilitated by illnesses since his childhood, he codified Patanjali’s yoga sutras in an innovatively dynamic yoga style which came to be known as Iyengar Yoga, winning millions of followers in more than 70 countries of the globe in the process. He set forth its principles in Light on Yoga (1966), which has since been regarded as the bible of yoga. The book has been translated into 19 languages and has sold more than three million copies. Most importantly, he opened the doors for his discipline, making it accessible to all regardless of class, caste and religion."
