"For Aurobindo, Yoga is not merely a particular discipline or philosophy, part of culture, science or religion as we know it. "All life is Yoga," as he boldly proclaims, meaning not just human life but the cosmic life. Yoga is the very inner spiraling movement of life towards the evolution of consciousness. This is not the outer life of the body but the inner life of the spirit, which can then take up the outer life of the body as part of a spiritual expression.Santosh Krinsky has endeavored to make Sri Aurobindo's teachings relevant and readable to the very different audience today, without compromising the essence of his teaching. I do not think that any other writer in American has better represented Aurobindo's teachings today than Santosh. This is a difficult task to be sure but not one that he has been able to do consistently and with depth of thought. The reader is guided through short episodes that can constitute a simple yet direct immersion into the heart of Aurobindo's teachings. Krinsky has approached The Synthesis of Yoga in four volumes of which this current book is the fourth final one, which addresses Sri Aurbindo's unique contribution of the "Yoga of Self-Perfection." This helps the reader understand the depths of Yoga and how it can be used to make fundamental changes in our being and character that are more important and enduring than mere outer changes in our body."-David Frawley, author of Yoga and Ayurveda
