This is one of the few truly great Buddhist books ever published in English. It would be hard to improve upon, and there will be no need for anyone to try their hand at this again in the future unless the English language changes substantially. The subject matter is sublime, a large collection of the original sutra teachings of Buddha, and the translators are the best in their field, scholar-practitioners with a long history of producing the clearest writings in this difficult field. And simply as a book it is of the highest quality, with exceptional binding, quality paper and excellent typesetting. You can't go wrong here.
