Ramayana 3.20

Then, by avenging fury spurred, Her mournful cry the heroes heard, And hastened, for the lady's sake, The wicked monster's life to take. Then Lakshman with resistless stroke The foe's left arm that held him broke, And Rama too, as swift to smite, Smashed with his heavy hand the right. With broken arms and tortured frame To earth the fainting giant came, Like a huge cloud, or mighty rock Rent, sundered by the levin's shock. Then rushed they on, and crushed and beat Their foe with arms and fists and feet, And nerved each mighty limb to pound And bray him on the level ground. Keen arrows and each biting blade Wide rents in breast and side had made; But crushed and torn and mangled, still The monster lived they could not kill. When Rama saw no arms might slay The fiend who like a mountain lay, The glorious hero, swift to save In danger, thus his counsel gave: "O Prince of men, his charmed life No arms may take in battle strife: Now dig we in this grove a pit His elephantine bulk to fit, And let the hollowed earth enfold The monster of gigantic mould."
