Abhidharma

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).

There are different types of Abhidharma literature. The early canonical Abhidharma works, such as the Abhidhamma Piṭaka, are not philosophical treatises but mainly summaries and expositions of early Buddhist 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 the Theravāda, Mahāyāna, and Vajrayāna schools of Buddhism.

The Belgian Indologist Étienne Lamotte described the Abhidharma as "Doctrine pure and simple, without the intervention of literary development or the presentation of individuals" Compared to the colloquial Buddhist sūtras, Abhidharma texts are much more technical, analytic, and systematic in content and style. The Theravādin and Sarvāstivādin Abhidharmikas generally considered the Abhidharma to be the pure and literal (nippariyaya) description of ultimate truth (paramattha sacca) and an expression of perfect spiritual wisdom (prajñā), while the sutras were considered 'conventional' (sammuti) and figurative (pariyaya) teachings, given by Gautama Buddha to specific people, at specific times, depending on specific worldly circumstances. They held that Abhidharma was taught by the Buddha to his most eminent disciples, and that therefore this justified the inclusion of Abhidharma texts into their scriptural canon.

According to Collett Cox, Abhidharma started as a systematic elaboration of the teachings of the Buddhist sūtras, but later developed independent doctrines. The prominent Western scholar of Abhidharma, Erich Frauwallner, has said that these Buddhist systems are "among the major achievements of the classical period of Indian philosophy."

Two interpretations of the term "Abhi-dharma" are common. According to Analayo, the initial meaning of Abhidharma in the earliest texts (such as the Mahāgosiṅga-sutta and its parallels) was simply a discussion concerning the Dharma, or talking about the Dharma. In this sense, abhi has the meaning of "about" or "concerning," and can also be seen in the parallel term abhivinaya (which just means discussions about the vinaya). The other interpretation, where abhi is interpreted as meaning "higher" or "superior", and thus Abhidharma means "higher teaching", seems to have been a later development.

Some Western scholars have considered the Abhidharma to be the core of what is referred to as "Buddhism and psychology". Other scholars on the topic, such as Nyanaponika Thera and Dan Lusthaus, describe Abhidharma as a Buddhist phenomenology while Noa Ronkin and Kenneth Inada equate it with process philosophy. Bhikkhu Bodhi writes that the system of the Abhidhamma Piṭaka is "simultaneously a philosophy, a psychology and an ethics, all integrated into the framework of a program for liberation." According to L. S. Cousins, the Buddhist sūtras deal with sequences and processes, while the Abhidharma texts describe occasions and events.
