It is said that there was a big temple of Chamunda Mata in Upkeshpur presently known as Osiya situated near Jodhpur, Rajasthan. The temple was known for chamatkars and therefore everybody prayed to Chamunda Mata. During navratri, buffaloes were butchered and their flesh was offered to please Chamunda Mata. Acharya Shri Ratna Prabh Suri stopped this practice of animal killing. The goddess got angry
because of this and she caused pain in the eyes of the Acharya. He did not do anything but continued with the suffering. Chamunda Mata was ashamed when she found that Acharya has not reacted to her act. Acharya told her to not allow killing of animals as offering to her. He said that she is doing her own harm by asking her devotees to offer flesh of buffaloes or other animals. She will have to face all the wrong done in her name. She was made goddess because of her good actions but now she will have to face the hell. The goddess got enlightened. She told Acharya that from today no such killings would be allowed in the temple. Even red colored flower should not be offered. She would accept Prasad and Lapsi. Her worship will be done by kesar, chandan (sandal wood) and dhup (incense sticks). She will be happy as long as people are devoted to Lord Mahavira. She would fulfill all prayer of her devotees. Seeing this transformation, Acharya named her as Sachchi Mata. From that day, Chamunda Mata became and known as Sachchiyay Mata. It is believed and said that Sachhiyay mata was devoted in the Bhakti of Mahavir Swami so much that she decided to build a temple for Mahavir Swami. The Mahavir Swami temple in Osiya is one of the largest worshipped Jain temple in western India. The temple is situated on the western outskirts of the village. It faces the north and stands within a walled enclosure. The temple complex has a main temple and seven small temple, four are located along the eastern side and three on the western side. Adjoining the Temple complex are dharmashalas and a School of Theology which is attached to the Temple trust. The temple is managed by Seth Mangalsinghji Ratansinghji Dev Ki Pedhi Trust and continually has been maintained as a pilgrimage shrine throughout its history.
