Svayambhu and the Sun he prayed, And the swift Wind to lend him aid, And Indra, sovereign of the skies, To bless his hardy enterprise. Then once again the chief addressed The Vánars from the mountain crest: “Swift as a shaft from Ráma’s bow To Rávaṇ’s city will I go, And if she be not there will fly And seek the lady in the sky; Or, if in heaven she be not found, Will hither bring the giant bound.”

In plain words: Hanuman prays to Svayambhu (Brahma, the creator), the Sun, the Wind, and Indra for help. Then he tells the other monkeys he will fly to Ravan's city like an arrow from Rama's bow, and if he can't find Sita there, he'll search the sky or even heaven, or bring Ravan back tied up.
