Vibhishana Leaves Ravana and Seeks Rama's Refuge
Vibhishana repeatedly advises Ravana to return Sita and avoid a destructive war, but Ravana rejects the counsel and humiliates him.
Vibhishana leaves Lanka with a small group of companions and approaches Rama's camp, creating debate among the vanara leaders about whether he can be trusted.
Rama decides to grant refuge to one who sincerely seeks protection. Vibhishana then becomes a crucial source of knowledge about Lanka, Ravana and the rakshasa forces.
