This volume contains a translation of Seventy Stanzas, a fundamental work of Nagarjuna on the Madhyamika system of Buddhist philosophy, along with a commentary on it from the Prasangika viewpoint by Geshe Sonam Rinchen. David Komito summarizes basic Buddhist doctrines on perception and the creation of concepts, which have traditionally served as the backdrop for Nagarjuna's teachings about how people consistently misperceive and misunderstand the nature of the reality in which they live and the means through which they experience it. This book will interest Buddhist practitioners, scholars, and psychologists who seek a deeper understanding of Buddhist psychology and epistemology.
