In plain words
The poet, to the Lord of Araṅgam: O First Cause, who swallowed the three worlds and brought them out again, O you who dwell in the great city of Araṅgam! See: through the pride that comes from having learned your name, though we have set no guard on our senses, we have flung the whole mass of our sins far away, and raising a cry of victory we roam about on the very heads of Yama’s men.
