The Abhidharma are a collection of Buddhist texts dating from the 3rd century BCE onwards, which contain detailed scholastic presentations of doctrinal material appearing in the canonical Buddhist scriptures and commentaries. 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" (paramārtha-satya).
