And short it is. At 125 pages, it is more like an essay. Because of this brevity, it is a wonderfully concise and clear explanation covering the origins, history, evolution and practice of Buddhism in all its forms and locations. I have been interested in Buddhism for many, many years and have read many books on the subject as well writings such as THE TIBETAN BOOK OF THE DEAD, and I must say this book is very easy to understand. If you have wondered about Buddhism, where it came from, or, say, the difference between Tibetan Buddhism and Zen Buddhism, read this highly informative yet simple pocket-sized book.
