Sri Tirumalai Krishnamacharya, who lived to be over 100 years old, was one of the greatest yogis of the modern era. Elements of Krishnamacharya's teaching have become well known around the world through the work of B. K. S. Iyengar, Pattabhi Jois, and Indra Devi, who all studied with Krishnamacharya. Krishnamacharya's son T. K. V. Desikachar lived and studied with his father all his life and now teaches the full spectrum of Krishnamacharya's yoga. Desikachar has based his method on Krishnamacharya's fundamental concept of viniyoga, which maintains that practices must be continually adapted to the individual's changing needs to achieve the maximum therapeutic value.
