I read this over the past few wks in conjunction with a 6-wk class on the heart sutra at a local zen ctr. Red Pine has a fluid, informative writing style. He goes thru the relatively short sutra line-by-line, explaining words, their meanings, and interpreting the text. It's helpful that he also includes interpretation of each line from prior authors/historians. There's an excellent, long, well written glossary at the end that explains many Sanskrit and Buddhist words and their meanings. This alone would make the book worth its price. For those just exploring the heart sutra or wanting to study it in depth, this book is highly recommended.
