What yoga can do for the spine is presented from a combination of the Western anatomical perspective and the most modern yoga techniques Your Spine, Your Yoga is a masterpiece that bridges the gaps between scientific principles of movement, body function and yoga practice. This book unlocks the cages in which the Western view of yoga has unwittingly managed to confine itself. Not too many people or yoga books I know are able to capture the messages Bernie Clark delivers informatively, creatively and resourcefully. His brilliance and yoga experience create the conduit for delivery. Bernie boldly challenges the myths around movement terms (posture, stretching, flexibility, stress, strain, stability) with scientific clarity and reasoning. The craft of this book exposes how the architectural design of the body enables it to be fluid and rhythmic with yoga practice. This book is a truly innovative contribution integrating scientific principles, the body's functional characteristics and yoga practice. I really admire the organization and presentation of the material, particularly the special sections (e.g., It's Important, Notes to Teachers, It's Complicated) highlighting the important facts. It's a challenging task Bernie has undertaken, and in my view he has accomplished his goal to deliver a game changer in the yoga field. It's a groundbreaking resource to cherish.
