Several of you asked what books I'm reading on Buddhism. Here are a few I use for research that I've had in my collection for years. Most are texts used at university. They help me to get my facts right! I like to give some historical background before I talk about the *art*.
The first is Religions of Asia. The general editor is Robert K.C. Forman and is the third edition. It was used as a text.
The next is my all time favorite for figuring out the iconography of Buddhist art. Reading Buddhist Art: An Illustrated Guide To Buddhist Signs and Symbols by Meher McArthur, published by Thames and Hudson, 2002.
India:The Cultural Companion by Richard Waterstone is a book I found remaindered at Barnes and Noble. This book describes the main themes in the Hindu, Buddhist, Jain and other spiritual traditions of India.
The Buddhist Religion: A Historical Introduction (fourth edition) by Robinson and Johnson was used as a textbook. This may be my favorite as far as historical information on the Buddhist tradition worldwide.
I don't know if this helps anyone! There are others in our library. Many art books from the Met.
Loads of books on the Dalai Lama and Tibetan Buddhism.
