In plain words
The poet, of Tirumāliruñcōlai: The hill of the mighty one, who chased down Rukmī when he ran in pursuit to win back the lady Rukmiṇī, seized him, set him on the chariot and shamed him [shaving his head], is wondrous Māliruñcōlai, where the koṉṟai trees standing on the slopes heap up broken golden rings and coins and gladly give away gold [their golden flowers and petals].
