tenopāyena kākutsthaḥ setubandhamakārayat |

In thy army there is a monkey of the name of Nala, who is a skilful mechanic. And endued with great strength, Nala is the son of Tashtri, the divine artificer of the Universe. And whether it is wood, or grass or stone, that he will throw into my waters, I will support the same on my surface, and thus wilt thou have a bridge (over which to pass)!' And having said these words, the genius of the Ocean disappeared. And Rama awaking, called Nala unto him and said, 'Build thou a bridge over the sea! Thou alone, I am sure, art able to do it!' And it was by this means that the descendant of Kakutstha's race caused a bridge to be built that was ten Yojanas in width and a hundred Yojanas in length. And to this day that bridge is celebrated over all the world by the name of Nala's bridge. And having completed that bridge, Nala, of body huge as a hill, came away at the command of Rama.
