Kishkindha Kand — The fourth book, Kishkindha Kand, describes the meeting of Hanuman with Rama, the destruction of the vanara king Vali and the coronation of his younger brother Sugriva to the throne of the kingdom of Kishkindha.
The Kishkindha Kanda is set in the monkey citadel Kishkindha. Rama and Lakshmana meet Hanuman, the greatest of monkey heroes and an adherent of Sugriva, the banished pretender to the throne of Kishkindha. Rama befriends Sugriva and helps him by killing his elder brother Vali thus regaining the kingdom of Kiskindha, in exchange for helping Rama to recover Sita. However Sugriva soon forgets his promise and spends his time in debauchery. The clever monkey Queen, Tara, calmly intervenes to prevent an enraged Lakshmana from destroying the monkey citadel. She then eloquently convinces Sugriva to honor his pledge. Sugriva then sends search parties to the four corners of the earth, only to return without success from north, east and west. The southern search party under the leadership of Angad and Hanuman learns from a vulture named Sampati that Sita was taken to Lanka.
