Sri Krishnamacharya (1888-1989) was one of the greatest yogis of the last century. A. G. Mohan was a personal disciple of this great master for nearly two decades, spanning 1971-1989. He wrote down thousands of pages of verbatim notes during his studies with his guru. This book is a unique offering of lectures from Krishnamacharya in his own words, with the characteristic style and the specific terms and language he preferred. It is a special presentation of his insights on traditional yoga, including materials that have never been released before. The Mohans provide the reader a direct connection to the master's teachings through this work.
