A student in one of my classes, relatively new in her yoga practice, was asking about more info for yoga – yoga beyond the asanas. So I went to my personal library looking for some wide scope, introductory texts. Here’s what I took off the shelf:  Light on Life: the yoga journey to wholeness, inner peace, and ultimate freedom, by BKS Iyengar; The Heart of Yoga; developing a personal practice, by TKV Desikachar; and also thought of Integral Yoga Hatha, by Sri Swami Satchidananda. Wondering what readings lit the spark for others.
