When Bharata and Shatrughna returned, they learned that Kaikeyi had sent Rama into exile at Manthara's urging.
"But why did Rama agree to this madness?" exclaimed Shatrughna.
Then he saw Manthara, looking ridiculous in a fine new gown and fancy jewelry.
He grabbed her by the hair. "You'll die for this!" he shouted, dragging her across the floor towards Bharata. "Kill her, brother!" he shouted.
"No," Bharata replied. "Wicked as she is, she is a woman, and women are not to be killed. Otherwise, I would kill my own mother for her wicked deed. Rama forgave them; so must we."
