I have just gotten about halfway through reading/studying this book, and is very well written and easy to understand. Recommend those that want to read/study this to be somewhat familiar with Tibetan Buddhism though. I do not have much else to say about this as again, I have just gotten to the halfway point of book.
This book is an excellent resource and can be highly recommended to those preparing to take a Kalachakra initiation, such as the upcoming one in Toronto, April-May 2004. HH the Dalai Lama gives one or two Kalachakra initiations every year, so this book should be very valuable in future as well.
The book is comprised of two parts: an introduction by Jeffrey Hopkins (first 150 pages) and the commentary/teaching of the Dalai Lama throughout the actual initation (the rest of the book), plus a few texts on 6-session guruyoga and a sadhana at the end.
The introduction is excellent, explaining the sutra and tantra path, with a wonderful chapter on emptiness that is very clear and concise, and one of the best explications I have seen! This section alone is worth the price of the book. It explains the Kalachakra mandala (and there are some good color glossy photos inside) with all the deities as well.
The second section is even more incredible, as this is the actual text of what HH the Dalai Lama explained throughout the actual initiation. This would be very valuable for those preparing for such an initiation, or perhaps wanting to go back to understand it more deeply.
Combined, these two sections make this book invaluable. It is also beautifully made, with a great glossy cover, very durable, and glossy pages that are nice to read. Treasure it!
