Sarvārthasiddhi
Sarvārthasiddhi is a famous Jain text authored by Ācārya Pujyapada. It is the oldest extant commentary on Ācārya Umaswami's Tattvārthasūtra (another famous Jain text).[1][2] Traditionally though, the oldest commentary on the Tattvārthasūtra is the Gandhahastimahābhāṣya.[3] A commentary is a word-by-word or line-by-line explication of a text.
