n the 15th century is one of the most well-known texts on physical yoga. This translation offers unique perspectives and insight from Sri T. Krishnamacharya, who had perhaps the most influence in physical yoga in the modern era. Drawing upon extensive notes of private studies with Krishnamacharya, his long time student, A. G. Mohan, presents critical analysis unavailable in any other translation to date. This translation includes summaries, notes on which practices may be more or less useful or even harmful, and comparisons to the Gheranda Samhita. This book is a worthwhile read and companion to any serious yoga aspirant, especially those interested in knowing what one of the most influential yogis of the modern times had to say on the esoteric practices of hatha yoga: on pranayama, mudras, and bandhas.
