This book examines the Bhadrakar¿tr¿-s¿tra, an important representative of early Buddhist rak¿¿ literature, and thereby contributes to the investigation of this literary genre. This work ultimately presents an edition, partial reconstruction, and translation of the two extant Sanskrit manuscripts found in Central Asia, as well as a critical edition and translation of the Tibetan version of this text. Special focus is also given to the Chinese and Tibetan variants of the mantras. Moreover, it highlights specific rak¿¿ elements, formal features, and linguistic and semantic patterns of the Bhadrakar¿tr¿-s¿tra. These are crucial for the understanding of the peculiarities of its language, as well as its textual development and classification among rak¿¿ literature.
