Following Kabandha's suggestion, Rama and Laxmana came to
the Rishyamooka forest where Sugreeva lived with his army of monkeys.
Thinking they might be Bali's spies, Sugreeva became worried. He ordered
his loyal minister Hanuman to find out. Hanuman took the form of a Brahmin
and went to the brothers. Seeing Rama he knew that he could not be a
wicked spy. At once changing into his original form he asked the brothers
to introduce themselves. When Rama and Laxmana told him their story,
Hanuman bowed respectfully and said he was Vayu's son and also the exiled
king Sugreeva's deputy. On hearing that Rama and Laxmana had come
searching for Sugreeva, Hanuman said it would be an honour to help Rama
to free Sita from Ravana's clutches.
He promised Rama his eternal friendship, and then taking the brothers
on his sturdy shoulders he flew to Rishyamooka forest.
