The Rāmāyaṇa of Vālmīki 2.68.24

2.68.24

yasyāḥ putra sahasrāṇi sāpi śocati kāmadhuk
kiṃ punar yā vinā rāmaṃ kausalyā vartayiṣyati

He saw her weep whose offspring feed
In thousands over hill and mead,
And knew that in a mother's eye
Naught with a son, for love, can vie.
He deemed her, when the tears that came
From her sad eyes bedewed his frame,
Laden with their celestial scent,
Of living things most excellent,
If she these tears of sorrow shed
Who many a thousand children bred,
Think what a life of woe is left
Kaus'alyá, of her Ráma reft.
An only son was hers and she
Is rendered childless now by thee.
Here and hereafter, for thy crime,
Woe is thy lot through endless time.
And now, O Queen, without delay,
With all due honour will I pay
Both to my brother and my sire
The rites their several fates require.
Back to Ayodhyá will I bring
The long-armed chief, her lord and king,
And to the wood myself betake
Where hermit saints their dwelling make.
For, sinner both in deed and thought!
This hideous crime which thou hast wrought
I cannot bear, or live to see
The people's sad eyes bent on me.
Begone, to Dandak wood retire,
Or cast thy body to the fire,
Or bind around thy neck the rope:
No other refuge mayst thou hope.
When Ráma, lord of valour true,
Has gained the earth, his right and due,
Then, free from duty's binding debt,
My vanished sin shall I forget.'
