I was surprised to see that the item was used. Advertised as new. Would have liked the new ones stead got used.

This is the definitive watershed work that brought Buddhism to the West and explains it in a manner that's very easy for Westerners to understand. It is a wonderful book that uses a question and answer structure like the Catholic Catechism to enlighten the reader on the Buddhist faith. It covers every aspect of Buddhism and there's much to learn from it whether you are a beginner or a master or from the East or the West. I strongly recommend this book. I got so much out of it. This book answers a lot of very important questions, including ones that I have had for some time. It's been a real blessing to me.

Positive

Too many characters that appear for a sentence or two and then just vanish into the London fog of the late 19th century.
