Theravāda AbhidhammaThe Theravāda Abhidhamma is a scholastic systematization of the Theravāda school's understanding of the highest Buddhist teachings (Abhidhamma). These teachings are traditionally believed to have been taught by the Buddha, though modern scholars date the texts of the Abhidhamma Piṭaka to the 3rd century BCE. Theravāda traditionally sees itself as the vibhajjavāda ("the teaching of analysis"), which reflects the analytical (vibhajjati) method used by the Buddha and early Buddhists to investigate the nature of the person and other phenomena.
Pali CanonThe Pāli Canon is the standard collection of scriptures in the Theravada Buddhist tradition, as preserved in the Pāli language. It is the most complete extant early Buddhist canon. It derives mainly from the Tamrashatiya school. During the First Buddhist Council, three months after the parinibbana of Gautama Buddha in Rajgir, Ananda recited the Sutta Pitaka, and Upali recited the Vinaya Pitaka. The Arhats present accepted the recitations, and henceforth, the teachings were preserved orally by the Sangha.
AbhidharmaThe 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.
Pali literaturePali literature is concerned mainly with Theravada Buddhism, of which Pali is the traditional language. The earliest and most important Pali literature constitutes the Pāli Canon, the authoritative scriptures of Theravada school. Pali literature includes numerous genres, including Suttas (Buddhist discourses), Vinaya (monastic discipline), Abhidhamma (philosophy), poetry, history, philology, hagiography, scriptural exegesis, and meditation manuals. The Pali language is a composite language which draws on various Middle Indo-Aryan languages.
