The Dhammasaṅgaṇī (Pāli; 'Collection of Dhammas') is a Buddhist scripture, part of the Pali Canon of Theravada Buddhism. It is the first of the seven books of the Abhidhamma Piṭaka. It contains a detailed enumeration of all phenomena.
This introduction in a way may be regarded as a brief introduction to the Abhidhamma Piṭaka as a whole. It is in two parts. The first part is about Abhidhamma and the second part is about Dhammasaṅgaṇī.
