Unlike Hessel, I give high marks to the work of Jean-Marc Vivenza appeared some years ago. I read and reread this book that provides accurate insight on the contribution of Nagarjuna in Buddhist thought, especially the notion of emptiness. Indeed if it can not bring anything or nearly a practitioner, spiritually (in this case read the texts directly from the Indian thinker that are very affordable) it remains a very good tool philosophically, and can track, translate and locate in time, changing schools in their time, understanding what made the difference between Madhyamika and Yogachara, and most of the Mahayana, why and how Buddhism would become what he became later . To be considered an introduction, not a commentary on Nagarjuna (although ...) it will undoubtedly help the student, the researcher or the curious. A possibly completed by the book Claire Petitmengin "The path of the Middle".
