I have a soft spot for this volume since it was a core text in my YTT training. I think it's a good introduction to the Sutras. Front material puts what you're about to read into perspective. The poetic reading gives a feeling for what the verses are about from the interpreter's point of view. Next is a useful summary breaking down chunks of text and what they concern. Following the summary is my favorite section, which breaks down the individual Sanskrit verses word by word as though you were looking up the individual definitions in a Sanskrit dictionary (except you don't have to put in the hours of work). I had a lot of fun poring over these definitions, putting together my own interpretations of how they fit together and what they could mean. Definitely a book you can read repeatedly in small sections or large, and gain something new with each foray.
