The Authentic Yoga by P. Y. Deshpande is a very fine modern-day example of the evolving science of Yoga. In this book, P. Y. Deshpande takes the Yoga Sutras of the great sage Patanjali, which cover all aspects of human well-being, and expands them into a comprehensive explanation of Yoga.
To complement this extraordinary understanding, in an additional chapter Daaji introduces us to the next evolution of yogic practices that allow us to experience the impact of Yoga in our lives at all levels – physical, mental, emotional, and spiritual.
