In plain words
The poet, of Tirumāliruñcōlai: The hill of the sapphire-coloured one, who grew up [in Āyppāṭi] while Kaṃsa and Kāliya, the elephant [Kuvalayāpīḍa], the marutu trees and the bull [Ariṣṭa] all fell by their own treachery, is Tirumāliruñcōlai, where the serpent that spits venom rears up, reaches the cool, great full moon resting on the peak, and gropes at it with its red flaming tongue, taking it for its food.
