Being a master in disciplines, Krishnamacharya was offered high scholastic positions in great institutes of learning and in courts of Kings. But he chose to be a teacher, the promise he made to his yoga teacher.
On many occasions he demonstrated the world the great potentials of yoga, in different areas of health and control over oneself. The most prominent among them was being able to stop the heart beat for more than two minutes, using yogic practices. With his vast learnings in yoga as well as other systems of Indian philosophy, he emphasized that the practice of yoga must be adapted to the individuals, and not the individual to yoga. This was probably one of his most significant contributions in the field of health and healing, through yoga.
Krishnamacharya lived over a hundred years and continued to teach till the last few days before his death.
