The monograph is dedicated to the work of the Second Buddha, the founder of the Great Way (Mahayana) - Nagarjuna (II-III centuries). After a brief study of sources about the life and work of Nagarjuna, translations of 12 of his treatises are published, including the Buddhist lexicon Dharma Sangraha. Each translation is preceded by an introductory article and accompanied by Nagarjuna auto-commentaries, if any survive, as well as interpretations by celebrated Buddhist commentators and Buddhist scholars. The appendix includes the translation of the "Diamond Sutra" from the series of sutras "Improving Wisdom" ("Prajnya-paramita"), the forerunner of which is Nagarjuna, and the Dictionary of Indo-Tibetan and Russian Buddhism. The published book consists of an introduction, six chapters, an appendix, and a bibliography.
