Grammatical Analysis
Dhammasaṅgaṇī: [f.] Enumeration of Phenomena; Classification of Dhammas. Formed by dhamma (phenomenon, ultimate reality) + saṅgaṇī (grouping, enumeration, compilation).
Orthodox Definition
The Dhammasaṅgaṇī is the first book of the Abhidhamma Piṭaka and serves as the fountainhead of all Theravāda psychology.
Instead of teaching with stories or metaphors, the Dhammasaṅgaṇī opens with the Mātikā—a massive matrix of 122 categories that classifies absolutely everything in the universe. The most famous triad is: wholesome phenomena (kusalā dhammā), unwholesome phenomena (akusalā dhammā), and indeterminate phenomena (abyākatā dhammā).
The book then exhaustively defines every single state of consciousness (citta) and its accompanying mental factors (cetasika) across the sensual, fine-material, immaterial, and supramundane spheres. It then systematically categorizes all material form (rūpa). It is essentially the periodic table of elements for the Buddhist mind.
