Umaswati

Umaswati, also spelled as Umasvati and known as Umaswami, was an Indian scholar, possibly between 2nd-century and 5th-century CE, known for his foundational writings on Jainism. He authored the Jain text Tattvartha Sutra (literally '"All That Is", also called Tattvarthadhigama Sutra). Umaswati's work was the first Sanskrit language text on Jain philosophy, and is the earliest extant comprehensive Jain philosophy text accepted as authoritative by all four Jain traditions. His text has the same importance in Jainism as Vedanta Sutras and Yogasutras have in Hinduism.

Umaswati is claimed by both the Digambara and Śvētāmbara sects of Jainism as their own. On the basis of his genealogy, he was also called Nagaravachka. Umaswati was influential not only in Jainism, but also other Indian traditions over the centuries. The 13th- to 14th-century Madhvacharya, founder of Dvaita Vedanta school of Hindu philosophy, for example referred to Umaswati in his works as Umasvati-Vachakacharya. Some in the Digambara Jain tradition believe him to be the chief disciple of Acharya Kundakunda. However, this is disputed by some Western scholars.

Umaswati, was an Acharya (head of the monastic order, teacher) and therefore one of the Pañca-Parameṣṭhi (five supreme beings) in Jaina tradition. The theory mooted by Umaswati is that rebirth and suffering is on account of one's karma (deeds) and a life lived in accordance to vows of virtuous living with austerities cleanses this karma, ultimately leading to liberation. The main philosophy in Umaswati's Tatvartha Sutra aphorisms is that "all life, both human and non-human, is sacred."
