Core of the Yoga Sutras

According to HarperCollins:

Iyengar has devoted his life to the practice and study of yoga. It was Iyengar’s unique teaching style, bringing precision and clarity to the practice, as well as a mindset of “Yoga for all,” that has made it into a worldwide phenomenon. Iyengar, who turned 94 in December last year, and calls this his “last major work in this lifetime.”

In Core of the Yoga Sutras, he applies the philosophical core of yoga–the Yoga Sutras of Patanjali. These are 196 aphorisms forming the foundational text of yoga philosophy. Each sutra is presented as Sanskrit text, transliteration and English translation, followed by Iyengar’s unique commentary and authority only he can bring to the work.
