The Rāmāyaṇa of Vālmīki 1.65.26

1.65.26

tad etan muniśārdūla dhanuḥ paramabhāsvaram
rāmalakṣmaṇayoś cāpi darśayiṣyāmi suvrata

Not one of all the royal band
Could raise or take the bow in hand.
The suitors' puny might I spurned,
And back the feeble princes turned.
Enraged thereat, the warriors met,
With force combined my town beset.
Stung to the heart with scorn and shame,
With war and threats they madly came,
Besieged my peaceful walls, and long
To Mithilá did grievous wrong.
There, wasting all, a year they lay,
And brought my treasures to decay,
Filling my soul, O Hermit chief,
With bitter woe and hopeless grief.
At last by long-wrought penance I
Won favour with the Gods on high,
Who with my labours well content
A four-fold host to aid me sent.
Then swift the baffled heroes fled
To all the winds discomfited--
Wrong-doers, with their lords and host,
And all their valour's idle boast.
This heavenly bow, exceeding bright,
These youths shall see, O Anchorite.
Then if young Ráma's hand can string
The bow that baffled lord and king,
To him I give, as I have sworn,
My Sitá, not of woman born.'
