Ramayana 6.385

Then to his deadly string the pride Of Raghu's race a shaft applied. Sharp as a serpent's venomed fang Straight to its mark the arrow sprang, And from the giant's body shred With trenchant steel the monstrous head. There might the triple world behold That severed head adorned with gold. But when all eyes were bent to view, Swift in its stead another grew. Again the shaft was pointed well: Again the head divided fell; But still as each to earth was cast Another head succeeded fast. A hundred, bright with fiery flame, Fell low before the victor's aim, Yet Ravan by no sign betrayed That death was near or strength decayed. The doubtful fight he still maintained, And on the foe his missiles rained. In air, on earth, on plain, on hill, With awful might he battled still; And through the hours of night and day The conflict knew no pause or stay.
