Vyakhyana Saram:
Did He only rescue the world from Mahabali? Azhvar says that He is the smart one that protected the snake Sumukha who sought His protection by giving him for protection back to Garuda, his natural enemy - thereby keeping both His words "na kshamAmi" (that He will not tolerate the enemies of His devotees) and "na tyajeyam" (that He will not give up those who surrender to Him).
