Valmiki Ramayana 1.2.36

1.2.36

yāvad rāmasya ca kathā tvatkṛtā pracariṣyati
tāvad ūrdhvam adhaś ca tvaṃ mallokeṣu nivatsyasi

His every act to day displayed,
His secret life to none betrayed:
How Lakshman, how the giants fought;
With high emprise and hidden thought:
And all that Janak's child befell
Where all could see, where none could tell,
The whole of this shall truly be
Made known, O best of saints, to thee.
In all thy poem, through my grace,
No word of falsehood shall have place.
Begin the story, aud rehearse
The tale divine in charming verse.
As long as in this firm-set land
The streams shall flow, the mountains stand,
So long throughout the world, be sure,
The great Rámáyan shall endure.
While the Rámáyan's ancient strain
Shall glorious in the earth remain,
To higher spheres shalt thou arise
And dwell with me above the skies!
He spoke, and vanished into air,
And left Válmíki wondering there.
The pupils of the holy man,
Moved by their love of him, began
To chant that verse, and ever more
They marvelled as they sang it o'er:
'Behold, the four-lined balanced rime,
Repeated over many a time,
In words that from the hermit broke
In shock of grief, becomes a s'loke.'
This measure now Válmíki chose
Wherein his story to compose.
In hundreds of such verses, sweet
With equal lines and even feet,
The saintly poet, lofty-souled,
The glorious deeds of Ráma told.
