Umaswati

Vācaka Umāsvāti, also spelled as Vācaka Umasvati and known as Vācaka Umāsvāmī, was an Indian scholar, possibly between the 2nd and 5th centuries CE, known for his foundational writings on Jainism. He authored the Jainatext Tattvartha Sutra. According to historian Moriz Winternitz, Umāsvāti may have been a Śvetāmbara ascetic as his views correspond more with the Śvetāmbara sect than with the Digambara sect, and that the latter is 'hardly entitled to claim him.' Umāsvāti's work was the first Sanskrit language text on Jaina philosophy, and is the earliest extant comprehensive Jaina philosophy text accepted as authoritative by all four Jaina traditions. His text has the same importance in Jainism as Vedanta Sutras and Yogasutras have in Hinduism.
