Srimad Bhagavatam Canto 09, Chapter 10, Text 26

SB 9.10.26

ha hatah sma vayam natha
 loka-ravana ravana
kam yayac charanam lanka
 tvad-vihina parardita
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
O my lord, O master! You epitomized trouble for others, and therefore you were called Ravana. But now that you have been defeated, we also are defeated, for without you the state of Lanka has been conquered by the enemy. To whom will it go for shelter?
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Ravana’s wife Mandodari and the other wives knew very well how cruel a person Ravana was. The very word “Ravana” means “one who causes crying for others.” Ravana continuously caused trouble for others, but when his sinful activities culminated in giving trouble to Sitadevi, he was killed by Lord Ramacandra.
