Abhidharma

The Abhidharma are ancient (third century BCE and later) Buddhist texts which contain detailed scholastic presentations of doctrinal material appearing in the Buddhist sutras. It also refers to the scholastic method itself as well as the field of knowledge that this method is said to study.

Bhikkhu Bodhi calls it "an abstract and highly technical systemization of the [Buddhist] doctrine," which is "simultaneously a philosophy, a psychology and an ethics, all integrated into the framework of a program for liberation." According to Peter Harvey, the Abhidharma method seeks "to avoid the inexactitudes of colloquial conventional language, as is sometimes found in the Suttas, and state everything in psycho-philosophically exact language." In this sense, it is an attempt to best express the Buddhist view of "ultimate reality" (paramartha-satya).

There are different types of Abhidharma literature. The early canonical Abhidharma works (like the Abhidhamma Pitaka) are not philosophical treatises, but mainly summaries and expositions of early doctrinal lists with their accompanying explanations. These texts developed out of early Buddhist lists or matrices (mātṛkās) of key teachings.

Later post-canonical Abhidharma works were written as either large treatises (śāstra), as commentaries (aṭṭhakathā) or as smaller introductory manuals. They are more developed philosophical works which include many innovations and doctrines not found in the canonical Abhidharma.

Abhidharma remains an important field of scholarship among both Theravāda and Mahayana Buddhists.
