to legends Tarakasura turned himself into lokakanthaka on obtaining
several boons. When life on earth became unbearable, the afflicted
Mother Earth and Surasura manavas met Lord Vishnu for relief. He
directed their to seek help from Lord Siva, who on hearing their
sight deputed Kumaraswamy to kill Turakasura, giving clue for
flooring him. Accordingly Kumara, the Field marshal of the celestial
army hit Taraka with his spear on the Chest, bearing the Sivalinga.
At once it was split into five parts and fell at different places.
And them each place became an arama of unparalleled spiritual
importance. Thus came into existence the Pancharamas Draksharama
Bhimarama, Ksheerarama, Somarama and finally Amararama. Grand
shrines were built in these places and Sivalingas were installed
with due agamic rites for the benefit of devotees of both
terrestrials and celestials.
