According to Hindu mythology, in Satya Yuga Parvati (Sati), the daughter of Dakha Prajapati married to “Yogi” (Lord Shiva) against the wishes of Dakha Prajapati. So to take revenge with Lord Shiva, Dakha Prajapati performed a Vrihaspati yagna where he invited all the deities except Lord Shiva & Sati. But knowing the fact that Sati was not invited, she expressed her desire in front of Lord Shiva to attend the yagna. Lord Shiva tried his best to stop her, but she was not able to understand anything, so Lord shiva had to allow her to attend the Yagna. Where, being an uninvited guest she was not given any respect. Infect, her father insulted Lord Shiva which was unbearable for Sati. So on discovering her father’s trick for humiliating her husband she jumped into the Yagna and committed suicide.

Seeing the burning body of Sati, Lord Shiva destroyed Dakha Prajapati’s Yagna. He carried the remains of her body with grief profound and danced the dance of destruction through the Universe. The places where the parts of her body fell were recognized as Shakti Peeths. In Purnagiri the Naabhi (Naval) part of Sati fell where the present Purnagiri Temple is situated. People come here to worship the Devi in large numbers round the year.
