Sita’s place of captivity was thus known to the Vanar; but how to reach Lanka--separated as it was from the mainland by an arm of the sea--became the urgent problem of the hour to the Vanar commanders of the army of the south. If Sita was to be restored to the arms of Rama, it was absolutely necessary that some one should get to Lanka as a spy, in order to ascertain the facts in regard to Sita’s captivity there, and to discover the strength of Ravana’s army and his means of resisting an attack from without. Ships or even boats were, in those primitive times, not to be thought of; but the monkey could _leap_, and so it was proposed that some leader of the race should essay the rather long jump across the strait which separated Lanka from the continent. Who was so fitted for this undertaking as the son of the wind-god, the redoubtable Hanuman? Accordingly, after a great deal of boasting, Hanuman, assuming a gigantic size, took the flying leap. The gods were well disposed towards his brave venture, but there were also enemies on the path, who endeavoured to stop him on his way. One of these was Surasa, the mother of the Nagas, who, rushing upon him with wide-extended jaws, mockingly told him that he must pass through her mouth before proceeding any further on his journey. Hanuman dilated his person till his stature attained many leagues, but the monster’s mouth grew larger still. The cunning monkey now suddenly contracted his dimensions to the size of a man’s thumb and jumped airily into and out of Surasa’s gaping mouth. He had fulfilled his enemy’s conditions and she good-naturedly acknowledged her defeat. His next opponent, a terrific she-dragon, the fierce Sinhika, marvellously caught his shadow as it glided over the sea, and in some mysterious way retarded his progress thereby. With open mouth she made a furious onslaught upon the wind-god’s son. Hanuman, equal to the occasion, craftily contracted his dimensions, and jumping into Sinhika’s cavern-like mouth, inflicted so much injury upon her that she died. After this interruption he continued his aërial journey to Lanka, probably making Sinhika’s carcass the base of a fresh leap towards the island, though this is not expressly mentioned by the poet. When he had reached the island-kingdom of Ravana, the Vanar spy, contracting his dimensions to those of an ordinary cat, found his way by moonlight within the golden walls of the city, and, lost in admiration, wandered about the wonderful streets of Ravana’s capital, where tonsured priests and mail-clad warriors mingled freely with bands of ascetics in deerskins, and fiends both foul and fair. Eluding the guards, Hanuman crept into the palace. Here everything was on a scale to astonish even the wind-god’s son, familiar with the glories of Kishkindha; but most of all did he find food for admiration in Ravana’s enchanted car, avowedly the most perfect work that had been produced by Visvakarma, the architect of the gods.
