A review by audreyloopy
Light on Yoga by B.K.S. Iyengar

3.0

It is literally the Bible of modern Yoga. Anyone who practices Hatha (or a derivative) will appreciate the in-depth dissections of the asanas and their proper alignment, the progressions that Iyengar offers, and the meditations on the significance of an informed asana practice.

It's dense, but an excellent reference.
