6000   years ago sage Agasthya Maharshi installed the idols of Sri  Meenakshi  Agasteswara  and  Sri Laxmi  Narsimha  at  holy SANGAM of  Krishna  and  Musi  rivers  in  Wadepalli  village  of  Miryalguda  Mandal.    For  thousands of years  the  temple  place remained   in dense forest. During the time of excavation the idols of Lord Shiva were found in the temple and reinstalled the same. Once  a  hunter was chasing a bird, the bird  wanted  to save its  life. So  it  hid behind the idol of  Lord  Shiva  by covering  it  with  its wings.  Lord Shiva appeared   to  the hunter and  asked him not to kill the bird. Lord Shiva assured the hunter that  he would offer his brain instead of bird.  Then  the hunter agreed   to him and had the brain of Shiva by inserting his fingers.   As  he did so, holes were made on his  head.   Goddess Ganga rose out of the holes, soon after this incident. There  are holes on the SIVA LINGAM in which 10  figures can be inserted.   Even  after taking large quantities  of  water from the  holes,  the level of water does not go down.  Once  Sri Shankaracharya visited the temple along with his diciples.They wanted to  find  out the reason as to why the water level is  not going down   therefore they tied a thread to spoon and dropped  it into the  hole  then it went inside deep and stopped.  When  they pulled up  the   thread,  they found blood stains  on  that,  then realised their mistakes and begged pardon from the God.
