The 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.
