The Abhidhamma is above all an investigation of the possibilities of the mind, and thus its most impressive achievement is the construction of an elaborate map revealing the entire topography of consciousness. Like all maps, the one devised by the Abhidhamma necessarily simplifies the terrain which it depicts, but again like any well-planned map its simplification is intended to serve a practical purpose. In this case the map is drawn up to guide the seeker through the tangle of mental states discerned in meditative experience toward the aim of the Buddha’s teaching, liberation from suffering.
