3.68.22

sa meruśṛṅgāgragatām aninditāṃ praviśya pātālatale 'pi vāśritām
plavaṃgamānāṃ pravaras tava priyāṃ nihatya rakṣāṃsi punaḥ pradāsyati

He over rocky height and hill,
Through gloomy cave, by lake and rill,
Will with his Vánars seek the prize,
And tell thee where thy lady lies.
And he will send great chieftains forth
To east and west and south and north,
To seek the distant spot where she
All desolate laments for thee.
He even in Rávan's halls would find
Thy Sítá, gem of womankind.
Yea, if the blameless lady lay
On Meru's loftiest steep.
Or, far removed from light of day,
Where hell is dark and deep,
That chief of all the Vánar race
His way would still explore,
Meet the cowed giants face to face
And thy dear spouse restore."
