The Swayambhu archamurthi now worshipped in the temple has a
fantastic background and is associated with Amalakan-the devout son
of Kasyapa Prajapati. The Purana reads thus - Amalaka designing to
lifting mankind from the samsarasagara through devotion did dirgha
tapas here. Power mad Devendra presuming Kasyapa's motive for
Devedrarapadivi tried to foil it with the help of celestial nymphs -
Rambha, Urvasi etc.
His rock-like firmness did not allow any dent.
He then approached Kasyapa to dissuading his son from that desire;
Kasyapa acquainted him with the nobility of his son's penance for
achanchala bhakti - unstinted devotion only and not for any
transitory bhoga. Pleased with it, Devendra again enjoyed peaceful
nights. It has a strange reaction on the asuras.
