Ravana brought Sita to Lanka. He showed her his palace and riches. He showed
her his rakshasas army. He told her: "Look here, Rama cannot come here. Forget him.
There is no one more heroic and rich than I am. Become my queen and lead a happy
life."
Sita did not want even to talk to him. She held a blade of grass before her and looking
at it said: "Ravana, you have carried me to this place stealthily when Rama was not
present. If he was there at that time, you would have been destroyed. It looks as if your
life is now ended."
Ravana was enraged. He kept her in the Ashokavana garden and engaged demonizes to guard
her.
