Due to its culminating achievement in streamlining the structure of the whole exposition of the Abhidharma and due to its comprehensiveness, incorporating all the important Vaibhāṣika doctrines since the Vibhāṣā, as well as due its great value as a brilliant critique and insightful reevaluation of all the fundamental Sarvāstivāda doctrines developed up to its time, the Abhidharmakośa-bhāṣya, since its appearance in the late fourth century C.E., has been used in India as a standard textbook for the understanding not only of the Abhidharma doctrines but of the fundamental Buddhist doctrines in general, and has been hailed as the “Book of Intelligence”. In China, Japan and the Far-East as well, the Kośa has generally been highly treasured as a textbook of fundamental importance for Buddhist studies. What is new in this annotated translation?
