This is a fully annotated, critical English translation of Maitreyanatha's Universal Vehicle Discourse Literature (Mahayanasutralamkara), as transmitted to the fourth-century Indian Buddhist scholar-adept Ärya Asanga, along with its commentary (bhasya) by Asanga's brother Vasubandhu. A wellspring of the "magnificent deeds trend of the path," the Discourse Literature emphasizes the compassion side of Buddhist thought. This long-awaited work is the founding cornerstone of the AIBS'Tanjur Translation Initiative. Includes an introduction covering essential historical and philosophical topics, a bibliography, and detailed index.
