It is here fell Mother Sati's Brhamarandhra - the fontanels, the supposed quitting place of soul after death, when Mahavishnu's Sudarsan Chakra spilt the Sati's corpse borne by Lord Siva during the frenzied Thandavanrithya that made the planets go off the track and the worlds shook in fear as chaos that developed all on a sudden and robbed the sanity of the wisest en. 

Mother Sati's adharoshta - lower lip fell here and the presiding deity of the temple built later is called Pullara Devi.
