Ramayana 4.209a

He ceased: at King Sugriva's call Near came a Vanar strong and tall. Huge as a towering mountain, loud As some tremendous thunder cloud, A prince who warlike legions led: To him his sovereign turned and said: "Go, take ten thousand(660) of our race Well trained in lore of time and place, And search the eastern region; through Groves, woods, and hills thy way pursue. There seek for Sita, trace the spot Where Ravan hides, and weary not. Search for the captive in the caves Of mountains, and by woods and waves. To Sarju,(661) Kausiki,(662) repair, Bhagirath's daughter(663) fresh and fair. Search mighty Yamun's(664) peak, explore Swift Yamuna's(665) delightful shore, Sarasvati(666) and Sindhu's(667) tide, And rapid Sona's(668) pebbly side. Then roam afar by Mahi's(669) bed Where Kalamahi's groves are spread. Go where the silken tissue shines, Go to the land of silver mines.(670) Visit each isle and mountain steep And city circled by the deep, And distant villages that high About the peaks of Mandar lie. Speed over Yavadwipa's land,(671) And see Mount Sisir(672) proudly stand Uplifting to the skies his head By Gods and Danavs visited. Search each ravine and mountain pass, Each tangled thicket deep in grass. Search every cave with utmost care If haply Rama's queen be there. Then pass beyond the sounding sea Where heavenly beings wander free, And Sona's(673) waters swift and strong With ruddy billows foam along. Search where his shelving banks descend, Search where the hanging woods extend. Try if the pathless thickets screen The robber and the captive queen. Search where the torrent floods that rend The mountain to the plains descend: Search dark abysses where they rave, Search mountain slope and wood and cave Then on with rapid feet and gain The inlands of the fearful main Where, tortured by the tempest's lash, Against rude rocks the billows dash: An ocean like a sable cloud, Whose margent monstrous serpents crowd: An ocean rising with a roar To beat upon an iron shore.
