Abhidharma (Sanskrit) or Abhidhamma (Pali) are ancient (3rd century BCE and later) Buddhist texts which contain detailed scholastic reworkings of doctrinal material appearing in the Buddhist sutras, according to schematic classifications. The Abhidhamma works do not contain systematic philosophical treatises, but summaries or abstract and systematic lists. Buddhism portal'when they are seen after resolving them by means of knowledge into these elements, they disintegrate like froth subjected to compression by the hand. They are mere states (dhamma) occurring due to conditions and void. In this way the characteristic of not-self becomes more evident.'The Yogācāra masters inherited the mystical approach of the Prajñāpāramitā texts. However, they did not reject the validity of theoretical Abhidharma. Rather they attempted to construct a critical understanding of the consciousness that underlies all meaning, both mystical and theoretical. Their focus was on doctrine, but as it flowed from the practice of meditative centering (yoga), rather than as it was understood in acts of conceptual apprehension.Various Buddhist schools sprang to life, such as the school based on the three Mādhyamaka śāstras, the school based on the Abhidharmakośa, and the school based on the Satyasiddhi Śāstra. These all vied with each other, producing many wondrous offshoots, each giving rise to its own theoretical system.

The Abhidhamma works do not contain systematic philosophical treatises, but summaries or abstract and systematic lists. According to Collett Cox, Abhidhamma started as an elaboration of the teachings of the suttas, but later developed independent doctrines.
