I’m very excited about Mark Stephens new book, Yoga Adjustments: Philosophy, Principles and Techniques, which offers an invaluable service to the yoga community -- teachers, aspiring teachers and yoga students. As yoga’s popularity grows, we need our yoga teachers to mature as well, and Mark has given them a superb guidebook for making smart, safe, clear asana adjustments that further our understanding and deepen our experience of yoga.  In this way, the benefits of Mark’s expertise extends beyond the yoga community by demonstrating how healthy environments can be created in which any body can practice yoga with confidence.
