Rama's words made Sita feel angry and ashamed. "How can you treat me with such contempt?" she said, sobbing. "How can you have so little regard for womankind? Ravana overpowered and abducted me, but I was forever faithful to you, and I will prove it."
Sita turned to Lakshmana. "Build a fire!" she ordered.
Sita then prayed to Agni, the fire-god. "Demonstrate my faithfulness for all to see, and do not burn me."
Sita entered the fire.
It did not burn her.
Agni himself emerged from the fire, carrying Sita in his arms.
Rama received her with joy.
