Lord Rama Dwells in Hanumanji's Heart

"On entering the city of Lanka do all your work  with the king of Ayodhya dwelling in your heart. Poison is converted into nectar, foes become friends, the ocean shrinks to the size of a cow's hoof and fire becomes cool for such a person. And Oh Garuda! Mount Sumeru becomes like a speck of dust for him on whom Lord Ramchandra has cast his merciful glance just once." That is when Hanuman assumed a very minute form and invoking Rama, gained entry into the city. He rigorously searched every palace and saw innumerable warriors all over the place.

Ravana Deep Asleep in His Palace

Then he went to Ravana's palace. It was extremely majestic and defied description. Hanuman saw that Ravana was deep asleep but he did not find Janaki, Videhas' daughter, there. Thereafter he saw another palatial building with a separate temple of Hari built in it.

Lord Rama

That palace had sketches of Lord Ram's weapons (bows and arrows) drawn on it. Its splendour can not be described in words. Hanuman was overjoyed to see clusters of tulsi saplings planted here.

Vibhishana

Lanka is supposed to be the abode of hordes of demons. How could a virtuous person reside here? Hanuman rued over this point in his mind and that is precisely when Vibhisana woke up. He (Vibhishana) began to chant the name of Rama and Hanuman was delighted in his heart to know that he was a good man. He thought that he would certainly introduce himself because one 's mission never suffers at the hands of a holy man (and gains on the contrary).

Assuming the form of a brahmin, Hanuman called out to him. The instant he heard his call,Vibhishana got up and came there. Bowing respectfully, he asked about his well-being and said, “Oh Brahman Dev!Explain about yourself to me. Are you one of Hari's devotees? Because on seeing you great love is surging in my heart. Or are you Ramji himself, a loving friend of the poor, who has come to bless me with great good fortune ?(by giving me darshan at home)

Singing the Glories of Lord Rama

That is when Hanumån narrated the entire story of Lord Ramchandraji and revealed his own name.Soon after hearing this tale both of them were ecstatic and recollecting Rama's innate virtues, their minds became engrossed in love and joyous abandon.
