\r\n\r\n\r\nBy the mid-1950's word of Iyengar yoga spread in Europe, where he began teaching many new converts, including violinist Yehudi Menuhin and author Aldous Huxley.
\r\n\r\nThe popularity of Iyengar yoga spurred him to write a book called \"Light on Yoga,\" explaining the 216 yoga postures that formed what he called the science and art of yoga. The book became a global best seller with more than 3 million copies sold and has since been translated into 17 languages.
\r\n\r\nIyengar, easily recognizable by his bushy eyebrows and silvery locks of shoulder-length hair, practiced yoga until two months ago and even did headstands in his 90s.
\r\n\r\nIyengar yoga's physically challenging poses and breathing techniques have been adopted by mainstream medical practitioners to help patients suffering from diabetes, high blood pressure and chronic back pain.
\r\n\r\nIn 2004, Iyengar was named one of the 100 most influential people in the world by Time magazine.
\r\n\r\nIn a condolence message, Indian Prime Minister Narendra Modi described Iyengar as \"a fine guru, scholar and a stalwart who brought yoga into the lives of many across the world.\"
\r\n\r\nPresident Pranab Mukherjee said, \"The nation has lost a personality who devoted his entire life to the teaching and dissemination of India's ancient knowledge and wisdom to millions all around the world.\"
