Pranayama The Breath of Yoga
"Once again, Gregor Maehle has provided an invaluable resource for yoga students. I've read a dozen books on pranayama and taken workshops, all to little benefit in my practice.  With this book, the lights came on. As in his previous publications, Mr. Maehle combines his astonishing knowledge of yoga scripture with the most straightforward, most insightful, most eye-opening descriptions and explanations ranging from physiology and bio-mechanics to psychology and spirituality.  As I reread this book and ponder it, I am continually astonished by the depth of insight it provides.  I have come to believe that this will be the single most important book on yoga in the past century.  This is a life-changing contribution, for which I am profoundly grateful." - Paul M.
