In plain words
The poet, of Tirumāliruñcōlai: The hill of the beautiful, adorned one, who rid Śiśupāla, who reviled him naming fault upon fault, of his reckless prattle [showing him his beauty at his end], is Tirumāliruñcōlai: the chief hill for the clan of his servants, the lovely hill, the cool, great hill, the victorious hill, the fertile hill, the tall hill.
