"Thus addressed by that intelligent king of the monkeys, the high-souled Lakshmana became appeased, and he in his turn worshipped Sugriva. And accompanied by Sugriva, he returned to Rama on the breast of the Malyavat hill. And approaching him, Lakshmana informed him of the beginning already made in respect of his undertaking. And soon thousands of monkey-chiefs began to return, after having carefully searched the three quarters of the earth, viz., the North, the East and the West. But they that had gone towards the South did not make their appearance And they that came back represented to Rama, saying that although they had searched the whole earth with her belt of seas, yet they could not find either the princess of Videha or Ravana. But that descendant of Kakutstha's race, afflicted at heart, managed to live yet, resting his hopes (of hearing Sita's tidings) on the great monkeys that had gone towards the South.
