Perturbed by this situation and in order to bring Shiv to a state of normalcy, it was then Vishnu who decided to use his Sudarshan Chakra (the rotating knife s carried on his finger tip).
He dismembered Sati's body with the chakra into several pieces and wherever her body fell on the earth, the place was consecrated as a divine shrine oo Shakthi Peeth with deities of Sati (Parvati) and Shiva.
She was born on the 14th day of the bright half of the month of Mrigashīrsha, which marks the Shivarathri (Shiva's night) festival.
Shakta pithas are believed to have enshrined with the presence of Shakti due to the falling of body parts of the corpse of Sati Devi, when Lord Shiva carried it and wandered throughout the land in sorrow.
It is believed that the Neck of Sati Devi has fallen in Srihatta and the Shakti here is addressed as Mahalakshmi and the Kalabhairava as Sambaranand.
