In plain words
Amutaṉār, to those who ask him: On that day the Lord became a matchless lion, his fierce rage growing, and tore open the swollen golden chest of the sword-bearing asura [Hiraṇya]; the crop of that Lord's fame springs up and ripens in the mind of Rāmānuja. He cleared away the sickness of the deeds that cling to my body and gave me good knowledge, like a fruit in the hand.
