Sir — If millions around the world today swear by yoga, a large part of the credit goes to BKS Iyengar and his innovative methods. Iyengar, who went from being a disease-stricken child to one of the world’s foremost yoga teachers revered by the likes of Yehudi Menuhin, Jayaprakash Narayan, Jiddu Krishnamurti and Sachin Tendulkar, has passed away. Interestingly, Western celebrities such as actor Annette Bening, fashion designer Donna Karan and writer Aldous Huxley were among his students.
