Patanjali's Yoga Sutras based on the teaching of Srivatsa Ramaswami

I was excited to see this book, having already read Ramaswami's other books ("The Complete Book of Vinyasa Yoga", "Yoga for the Three Stages of Life" and "Yoga Beneath the Surface"). Ramaswami was a student of Krishnamacharya and one of the original trustees of the KYM in Chennai. Outside the immediate family, he was also Krishnamacharya's longest serving student, studying with his guru from 1955 to 1988.
Different editions of the Yoga Sutras offer different things - some are more accademic, some more poetic or inspirational. Some, I have to confess are muddled or confusing. This edition has clear word for word translations and Pam Hoxsey's notes - sometimes asking questions, sometimes expanding on a theme or imparting stories or little gems from the oral teachings of Ramaswami, which in turn are based on his studies with Krishnamacharya. Thus for example, we get sidenotes on Krishnamacharya's pranayama practice, on Buddhism and Vedanta and their relationship to Patanjali and many other fascinating topics.
I don't think this is necessarily a beginner's version - the notes are fairly brief (but to the point, rather like the sutras themselves). However, anyone who has some experience of studying the sutras - especially from this tradition, will find much of interest here.
