When the rainy season was drawing to a close, Rama fretted because Sugriva, King of the Vanars, was making no effort to collect his forces and prepare for the recovery of Sita. Instead, he drank wine and spent the days in merriment among his wives. At length Lakshmana visited the palace and threatened Sugriva with death, because he had broken his promise, whereat the monarch summoned speedily his great armies of apes and bears in countless numbers. Four divisions were then sent out to the north and the south, and eastward and westward, to search for Sita. Success attended the efforts of the army commanded by Hanuman. It chanced that his officers discovered on a mountain summit Sampati, the brother of Jatayus, King of the Vultures. He was wounded and helpless, because his wings had been scorched by endeavouring to soar to the sun so that he might fulfil a vain boast. Although stricken thus, Sampati could still see clearly over vast distances. He had beheld Ravana carrying away Sita across the ocean towards Lanka. This knowledge he communicated through his son to Hanuman. When he rendered such great service to Rama his wings began to grow, and he was enabled once again to take flight athwart the blue heaven. Hanuman then resolved to visit the distant island with purpose to discover where Sita had been hidden. Assuming gigantic form, he stood upon a mountain top and leapt seaward. The mountain shook when he sprang from it. Over the sea went the wind god's son and that swiftly. But demons endeavoured to arrest his progress through the air. Surasa, mother of the Nagas, rose up with gaping jaws, and cried: “Thou must needs pass through my mouth ere thou wilt go farther, O Hanuman.” The heroic Ape extended his bulk, but the Naga hag opened wider and wider her jaws to prevent him passing. Then Hanuman shrank to the size of a man's thumb, and leapt into her mouth and out of it again and again so as to fulfil her conditions, whereat the hag owned that she was defeated and allowed him to pass. Next arose the she dragon, Sinhika, who clutched the shadow of Hanuman and held him back. Wrathfully she sprang forward to devour him, but again the cunning Ape contracted himself, and entering her mouth, attacked her and wounded her so that she was slain.
