Trilinga temples are also known as Trilinga Desam, which points to “the country of the three lingas (Shivalingams).“
The mythicism was that Lord Shiva had been descended as Shivalingam on three sacred hills. The three sacred hills are:
- Kaleswaram in Telangana
- Srisailam in Rayalaseema
- Bhimeswaram or Draksharamam in Coastal Andhra
The three holy mountains are considered as the boundaries of the whole Telugu country, which is presently called Telangana.
It is said that in a Telugu literature named Andhra Kaumudi, Sri Andhra Vishnu, a mythical combatant by the name Viṣhṇu who became popular as a very courageous savior of his small kingdom, have created a gigantic wall, uniting Srisailam, Bhimeswaram, and Kaleswaram by the Mahendra mountains.
And it is stated that in the three mountains were the three-eyed Ishwara, the principal god Shiva, was found carrying the trident in His hand and was inscribed by a collection of divinities reposed in the form of three Shivalingams. And hence the three hills and its related temples are known as Trilinga Kshetras (temples) or Trilinga Desam.
The myth also says that in Andhra Vishnu was aided by the divine angels and confronted with Nishambhu, the great giant, for thirteen yugas (ages of life of the world) and ruined him in battle and held up His residence on the banks of river Godavari along with the sages (saints).
