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. In Navratri buffaloes were butchered. People used to give offerings of flash of buffaloes to please the Devi. The Acharya Shri Ratna Prabh Suri stopped this practice of animal killing. Because of this the goddess got angry and she created pain in the eyes of Sri Acharya. He did not do anything but continued with the suffering, when Devi found out that no reaction has taken place, she was ashamed. She asked forgiveness from the Acharya.
Acharya explained that, “You better not allow killing of animals as offering to you, by asking your devotees to offer you flashes of buffaloes or other animals you are doing your own harm. You will have to face all the wrong that are committed in your name, you have been made Goddess because of your good actions but now you will have to face the hell “ The Goddess got enlightened she told Acharya,” from today no more such killings would be allowed in the temple and even red colored flower shall not be offered. I will accept Prasad & Lapsi, my worship will be done by kesar, chandan (Sandal wood) and Dhup (incense sticks). I will be happy as long as people are devoted to lord Mahavira. I will fulfill all prayer of my devotees.’
Acharya told from today you are Sachhi Mata. From that day Chamunda mata became and known as Sachhiyay Mata.
