famous Holy shrines of Lord Shiva) in Andhra Pradesh..
It is now known as Someswara. Here Lord Shiva
manifested himself as Lord Someswara. The legend
is that once the Devathas (good spirits) were
defeated by the Rakshasas (demons or evil spirits)
by the name 'Tarakasura'.
The Devathas (good spirits) then got frightened
and went to Lord "Maha Vishnu" for help.
Lord Vishnu told them that Taarakasura was a great
Shiva bhaktha (worshipper of Lord Shiva) and a
devoted worshipper of Lord Shiva.
Lord Vishnu advised the Devathas (good spirits) to go and pray to Lord Shiva. Lord Shiva heard the pray of Devathas,(good spirits) also told them, that it would not be possible him to kill Tarakasura. Because he was a great Shiva bhaktha (worshipper of lord Shiva). Finally Lord Shiva deputed "Kumaraswami" (Murugan or Karthekeyan, one of the sons of Lord Shiva) lead the army of Devathas (good spirits) for a fight with Tarakasura. Kumaraswami (Murugan or Karthekeyan, is one of the son of Lord Shiva) also found himself unable to deal with Tarakasura (demon or evil spirits). Once again they go back to Lord Shiva and pray to him for Succor. Lord Shiva then told the Devathas (good spirits) that Tarakasura being a great bhaktha (great worshipper) that carried "Shivalinga" (Lord Shiva in the form of small statue). In his own throat and his very life was in the Shiva Linga. Hence he suggested that if they could break that Shiva Linga, Then Tarakasura would die.
