Aṭṭhasālinī-Aṭṭhakathā

The text opens with the Ganthārambhakathā and Nidānakathā, introducing the Abhidhamma tradition, the role of the councils, and the purpose of textual preservation. The main body follows the structure of the Dhammasaṅgaṇī through four principal divisions: Cittuppādakaṇḍa, which explains the arising and classification of consciousness; Rūpakaṇḍa, which analyzes material phenomena; Nikkhepakaṇḍa, which arranges dhammas by categories such as root, aggregate, sense-base, plane, meaning, dhamma, name, and grammatical form; and Aṭṭhakathākaṇḍa, which clarifies meanings and doctrinal applications. Together these sections provide a compact but highly technical exposition of Abhidhamma categories, emphasizing precision, classification, and the commentarial interpretation of the Dhammasaṅgaṇī.
