Yoga therapy is a big field, encompassing the entirety of yoga and its many practices along with aspects of Western medicine, Ayurveda, physiology, physical therapy, kinesiology, psychology, philosophy, spiritual development and more. No single volume can do it full justice, but Mark Stephens has done a yeoman's job to assemble much of the background information aspiring yoga therapists will need to understand. This book is smart, thoughtful and well-researched and doesn't shy away from presenting a strong ­— and sometimes provocative — point of view. I recommended it highly.
