It is believed from several pieces of evidence that the people of
Osian become Jain by
Acharya Ratnaprabhasuri, who had impressed the populace of the region with his supernatural powers. The Mahavira Temple is an important
tirtha for
Jains. According to an inscription found at
Sachiya Mata Temple dating back to 956 A.D., it was built during the
Gurjara-Pratihara dynasty by King Vatsaraja in 783 AD, making it the oldest surviving Jain temple in Western India. According to Jain legends,
Acharya Ratnaprabhasuri in ( BCE) restored the life of son of a prominent brahman following this even the villagers converted to Jainism and this place for origination of
Oswal community. Witnessing the power of
Ratnaprabhasuri Goddess
Chamunda was compelled to become a Jain vegetarian deity and became the protector deity of the temple, protecting devotees who worship image of Mahavira in the temple.
Ratnaprabhasuri then named her
Sachiya Mata as she truthfully advised
Ratnaprabhasuri to stay in Osian during
Chaturmas. Osian is an important Jain pilgrimage center for the Maheshwari and Oswal Jain communities. The (
Mahavira, महावीर) Temple, built here in A.D. 783, is an important
tirtha for
Jains built by
Gurjara Pratihara King
Vatsaraja. The
Sachiya Mata Temple also equally old and important situated on a hill north-east of
Mahavira Temple, enable us some clues to understand the social history of that period. This Temple was built by Utpaldev who is the brother of Raja Punj the son of King 'Bheemsain' (king of
Bhinmal). This has many decorative features of a Jain temple and its construction can be attributed to Jains. Jains worship this deity as a
samyaktvi () goddess and as protector of the land, of their clan of
Oswals and of the
Mahavira Jain temple, Osian. The
Shingavi, Baid, Bafna, Lunawat, Tated, Parekh, Karnavat and many other clans of Jain community conduct their 'Mundan-Sanskar' in
Sachiya Mata Temple. ==Demographics==
