Tattvārthādhigama Sūtra :
Umāsvāmin or Umāsvāti is the author of the Tattvārthādhigama Sutra or Tattvārtha Sūtra, the first Sanskrit work on Jaina philosophy. He lived in an early century of the Christian era. The Tattvärtha Sūtra is a manual for the understanding of the true nature of things. It is recognised as an authority by both the Śvetāmbaras and the Digambaras. It deals with Jaina logic, epistemology, psychology, ontology, ethics, cosmography and cosmology. It has a large number of commentaries, one being by the author himself. Karmapraksti and Pancasangraha :
The Karmapraksti by Sivasarmasūri and the Pañcasangraha by Candrarși are two important Prakrit treatises on the Jaina doctrine of karma. They, too, were composed during the early centuries. Both of them have been commented upon by Malayagiri. Siddhasena's Works :
Siddhasena Divakara was a great logician. He also belonged to one of the early centuries. Like Umāsvāti, the author of the Tattvārtha Sūtra, he too, is regarded by both the sects as one of their own. His works include the Sanınatitarka, the Nyayāvatāra and thirty-two Dvātrimsikās (twenty-two are available). The Sanınatitarka is an excellent Prakrit treatise on the theory of Nayas (ways of approach and observation). It also deals with the theories of knowledge and judgment. The Nyāyāvatāra (Sanskrit) is the earliest Jaina work on pure logic. The Dvātrimśikas (Sanskrit) are on different aspects of Jaina philosophy and religion. Siddhasena Divākara has really made a valuable contribution to Jaina philosophical literature. Samantabhadra's Works :
Samantabhadra's contribution to the philosophical literature of the Jainas is equally important. He is the author
