Dravyasaṃgraha (Devnagari: द्रव्यसंग्रह) (Compendium of substances) is a 10th-century Jain text in Jain Sauraseni Prakrit by Acharya Nemicandra belonging to the Digambara Jain tradition. It is a composition of 58 gathas (verses) giving an exposition of the six dravyas (substances) that characterize the Jain view of the world: sentient (jīva), non-sentient (pudgala), principle of motion (dharma), principle of rest (adharma), space (ākāśa) and time (kāla). It is one of the most important Jain works and has gained widespread popularity. Dravyasaṃgraha has played an important role in Jain education and is often memorized because of its comprehensiveness as well as brevity. Source: Wikipedia (en)
