Landing on the soil of Lanka, Hanuman shrank himself to an unnoticeable size and began his search for Sita. He peeped into every building in the city. He saw several streets with
houses in which Ravana had kept his collection of women from several parts of this world and other worlds. Since Ravana had grown indifferent to them after his infatuation
with Sita, he ignored his favorites completely and Hanuman noticed that in every house, women sat longingly, hoping for Ravana's return to their embraces. Hanuman presently came into an elaborate mansion with rich furnishings where he saw a woman of great beauty lolling in her bed while several attendants were fanning her.
"Here is the end of my quest," Hanuman said to himself,thinking that it might be Sita; he studied her features closely,recollecting again and again the description given to him by Rama. He was filled with pain and anger at the thought that Rama's wife was living in such luxury, perhaps after yielding herself to Ravana. He almost wept at the thought that while Rama was undergoing such suffering in his quest for his wife, she should live in luxury now. For a moment, Hanuman
felt that there was nothing more for him to do, and that all his plans to help Rama had come to an abrupt end.plans to help Rama had come to an abrupt end.
While he sat there on the roof unobtrusively watching, he realized he might be mistaken. Observing her further, he noticed several differences in the features of this woman. In
spite of her beauty she had a touch of coarseness. She slept inelegantly with her arms and legs clumsily flung about, with her lips parted; she snored; and she talked in her sleep
incoherently. "No, this could be anyone but the goddess I am seeking," Hanuman told himself with relief; and presently he understood that this was Ravana's wife, Mandodari.
Hanuman next moved on into Ravana's palace, observed him in his luxurious setting and, after satisfying himself that Sita was not imprisoned there, passed on. After exhausting
his search of all the buildings he decided to search the woods and gardens. He finally arrived at Asoka Vana. It was Ravana's favorite retreat, a magnificent park land with
orchards and grottoes and pleasure gardens. When Hanuman came atop a simsupa tree, he observed several rakshasa women, grotesque looking and fierce, armed with
weapons, sleeping on the ground. Sita was seated in their midst. He studied her closely: she answered all points of the description given by Rama. Now Hanuman's doubts were
gone; but it rent his heart to see her in her present state, unkempt, undercoated, with a single piece of yellow sari covering her body, and with the dust of many days on her.
Suddenly the rakshasa women got up from their sleep,closed in on Sita, and menaced and frightened her. Sitashrank away from them, but challenged them to do theirworst.
Presently the tormentors saw Ravana arriving and drew aside. He approached Sita with endearing words. He alternated between frightening and cajoling her into
becoming his prime mistress. But she spurned all his advances. Hanuman shuddered at the spectacle before him but was also filled with profound respect and admiration for Sita.
Eventually Ravana went off in a great rage, ordering the fierce women to be unrelenting and break her will. After he left, the women became so menacing that Sita cried, "O Rama! Have you forgotten me?" Presently the women retired and Sita made preparations to end her life by hanging herself from a nearby tree. At this moment, Hanuman slowly
appeared before Sita, fearful lest he startle her, and hurriedly narrated who he was and why he was there. He explained all that had happened these many months; he answered all her
doubts and established his identity. Finally he showed her Rama's ring. His assurances and his message proved a turning point in Sita's life. She gave him a single piece of
jewellery that she had saved (concealed in a knot at her sari- end), and requested him to deliver it to Rama as her memento. Before he left, Hanuman assumed an enormous stature,destroyed the Asoka Vana, and damaged many parts of Lanka, so as to make his visit noticed. When news of this depredation reached Ravana, he dispatched a regular army
to attack and capture this monkey, but it eluded them. Finally Ravana sent his son Indrajit, who caught and bound the monkey (for Hanuman allowed this to happen) and took him
captive to the court. Ravana questioned who he was and who had sent him to destroy this land. Hanuman utilized this opportunity to speak about Rama, advise Ravana to change
his ways, and warn him of imminent destruction at Rama's hands.
Ravana in great fury ordered him to be destroyed; but his brother Vibishana interceded, reminding him that it would be improper to kill a messenger, and saved Hanuman.
Whereupon Ravana had his tail padded with cotton soaked in oil and set it on fire. Hanuman extricated himself from his bonds and ran over the rooftops of all the mansions and other buildings, setting fire to Ravana's splendid capital.
After satisfying himself that he had reduced it to ashes (leaving the tree under which Sita sat untouched), he hastened back to Rama's camp and reported to him fully all that he had seen and done.
