A complete translation of Asanga's classic work on the distinguishing qualities of bodhisattvas that describes how to awaken, develop, and perfect the mind of enlightenment in the Great Vehicle, or Mahayana, Buddhist tradition. Arya Asanga, famous for having been the conduit through which the teachings contained in the Five Texts of Maitreya were received and recorded, is also considered to be the author in his own right of several other foundational works of Yog c ra philosophy. One of these, considered the definitive text of the Yog c ra school of Buddhism, is the encyclopedic synthesis of Mahayana Buddhist doctrines and practices known as the "Yog c rabh mi, " or "Stages of Spiritual Practice." The "Bodhisattvabh mi," or "Stages of the Bodhisattva Path," is one portion of that massive work, though it is considered a stand-alone text in the Tibetan traditions--for example, it is counted among the six core texts of the Kadampas. However, despite the text's centrality to the Yog c ra school and its seminal importance in the Tibetan traditions, it has remained unavailable in English except in piecemeal translations; Engle's translation will therefore be especially welcomed by scholars and students alike."
