Query: Great Iyengar book

This is a great book for the new and the familiar to yoga. This compilation of lectures is a more philosophical look at his yoga, unlike the more technical books Light on Yoga and Light on Pranayama. Although these last two are indispensible, in this book, Iyengar's love of yoga shines through his words. He develops the analogy of the eight limbs of yoga as a tree skillfully and beautifully. Really excellent!
