He is thought to have lived around 2nd cent. AD. It is likely that at this time, no clear division of the the Jain Sangha had emerged, and thus both sects may be right in claiming him.
This stability is largely due to Umasvati's Tattvarthasutra, 'Mnemonic Rules on the Meaning of the Reals,' a collection of aphorisms in sutra form written in the fourth or fifth century CE.
Umasvati codified epistemological, metaphysical, cosmological, ethical, and practical elements of Jainism that were to be found dispersed throughout the texts.
Gradually the relationship between the jiva and action as being material was developed and Umasvati drew on texts to show that physical, mental, and verbal activity, termed yoga by the Jains, causes the flowing in of karmic particles.
