In the Hindu epic Ramayana, Vibhishana is portrayed as the younger brother of Ravana, the king of Lanka. However, there are some variations in different versions of the story.
According to the Ramayana, Vibhishana was a righteous and virtuous person who disagreed with Ravana’s evil ways and policies. Vibhishana advised Ravana to release Sita, the wife of Lord Rama, whom Ravana had abducted. When Ravana refused to listen to him, Vibhishana left Lanka and sought refuge with Lord Rama.
Lord Rama, who was impressed with Vibhishana’s righteousness, accepted him and made him the king of Lanka after defeating Ravana in the war. Vibhishana helped Lord Rama in the battle against Ravana by providing valuable insights into Ravana’s strengths and weaknesses.
As for how Vibhishana cheated Ravana, there are different versions of the story. Some versions say that Vibhishana betrayed Ravana by revealing his weaknesses to Lord Rama. Other versions suggest that Vibhishana did not cheat Ravana but instead, he left Lanka because he could not bear to be associated with his brother’s evil deeds. Regardless of the version, Vibhishana is generally portrayed as a virtuous person who chose to side with righteousness and morality rather than his family ties.
