Abhidharma generally refers to the corpus of Buddhist texts which deals with the typological, phenomenological, metaphysical, and epistemological presentation of Buddhist concepts and teachings. The abhidharma teachings present a meta-knowledge of Buddhist sūtras through analytical and systemic schemas and are said to focus on developing wisdom among the three principles of training. The Abhidharma is presented alongside Sūtra and Vinaya as one of the three baskets of the teachings of the Buddha.
