Book 5 of 6 in a great series that aims to strike a middle ground (sorry, had yo do it!) between not being simply an introductory text on key topics of Buddhist thought nor being simply an overly scholastic presentation on the topic at hand. IMHO, Geshe Tashi Tsering strikes the perfect balance of speaking to an audience that is familiar with the Buddhist teachings and ready to explore these topics in more depth without losing focus on the pragmatic, practice focus of the tradition - the Buddhist path is all about personal transformation after all.
This book provides on one the best presentations written that provides that middle ground approach on a rather challenging topic that leaves the reader knowing that a true understanding and experience of emptiness is closer than one may think before reading this book. I can't recommend this book highly enough for those trying to experience the traditions vast teachings on this most profound topic.
