Hi. Some of you wanted a list of books on Hinduism. Here you are:
The Upanishads (Nigiri Press)
The Bavhavad Gita same press. Though this one I assigned for the class, by Bantam Press is pretty good too).
This copy of the Yoga Sutras (Patanjali) is very affordable.
The Dammaphada (Nigiri Press), translator Easwaran's clear language is quite good, he keeps the poetic essence.
