Subrahmanya Dwara Palakas
Idumban requested Lord Karthikeya to allow him to be installed as the Dwarapalakan for His temple. The legend of Idumban is as follows. Lord Siva presented Agasthya munivar with two mountain peaks called Sivagiri and Shakthigiri.
Upon Agasthya’s direction, his disciple, Idumban tied the two peaks to the ends of a big pole and carried them on his shoulders. He paused to rest at Palani where the hills got stuck to the ground. On one of the peaks was Murugan with whom Idumban fought to reclaim the hill.
Idumban was defeated and killed in the fight and upon being implored by Agasthiyar was restored to life. Idumban requested Murugan to allow him to be installed as the Dwarapalakan in the palani temple. The Kaavadi form of worship originates from this legend.
