This book is as good as or a little better than most introductory-type books. Just because I already knew most everything in it is not reason for me to say it was bad. I imagine someone who knew nothing of Hinduism would find this helpful, and they may have enough interest sparked as to be inclined to read some deeper material, according to their interest perhaps a book like “Dancing With Siva” by Satguru Sivaya Subramuniyaswami or some more Vishnu-oriented material…

There are so many things to be discovered about Hinduism. This is the tip of the iceberg, but not a bad place to start.
