In plain words
The poet, of what his eyes have seen: He cut away the hold of my ancient deeds, which lay on me like a burden, and made me one devoted to him; and not only that, he entered into me. What fierce and great penance did I do? I do not know. Is it not the chest of the Lord of Araṅgam, bearing Śrī and the necklace, that has taken this servant for its own?
