Kiskindhākānda - Canto 26

Requested by Hanumān to visit Kiskindhā, Śrī Rāma declines to do so on the ground of his having been prohibited by his father to enter the limits of a village or town and, directing that Sugrīva may be installed on the throne of Kiskindhā and Angada may assume the office of Prince Regent, he himself takes a vow to live in a cave till the end of the monsoon and leaves instructions to initiate a search for Sītā after the monsoon.
