Merutuṅga was a medieval scholar from present-day Gujarat in India and was a Śvētāmbara Jain monk of the Achal Gaccha.
[6] The Therāvalī of Merutuṅga is a Paṭṭāvalī that presents a chronology from Mahavira to the arrival of and invasion by the Sakas in India.
[7] The Ṣaḍdarśananirṇaya is a general exposition, a doxography of 6 contemporary religious philosophies (darśanas) during Merutuṅga's time: Buddhism, Nyāya, Sāṃkhya, Vaiśeṣika, Mīmāṃsā, and Jainism.
It is unique among medieval Jain doxographies in that it presents refutations on non-Jain positions found in the other philosophies.
The work has survived with a bhāṣya, likely written by Merutuṅga himself, and is a charita, a biography, of five great figures in Jainism: Ṛṣabhadeva, Neminātha, Śāntinātha, Pārśvanātha, and Mahāvīra.
