"Mu Soeng's The Heart of the Universe is a brief, thought-provoking commentary on the Heart Sutra. In his introduction, the author, who is the scholar in residence at the Barre Center for Buddhist Studies, reminds the reader that the sutra has a history, and that all who have read--and chanted--it have done so within a specific cultural context. For Soeng, quantum physics--the scientific insight that the basic particles of matter are actually in constant flux-informs how the sutra is understood in the modern West. Of course, any discussion of the Heart Sutra is going to center on the concept of emptiness--the Mahayana theory that all phenomena are without fixed and independent identity. Soeng presents his fascinating discussion of emptiness early in the book, leaving little to say when discussing the famous line 'form is emptiness, emptiness is form' in his line-by-line commentary."
