The Rāmāyaṇa of Vālmīki 2.47.3

2.47.3

jāgartavyam atandribhyām adya prabhṛti rātriṣu
yogakṣemo hi sītāyā vartate lakṣmaṇāvayoḥ

When evening rites were duly paid,
Reclined beneath the leafy shade,
To Lakshman thus spake Ráma, best
Of those who glad a people's breast:
'Now the first night has closed the day
That saw us from our country stray,
And parted from the charioteer;
Yet grieve not thou, my brother dear.
Henceforth by night, when others sleep,
Must we our careful vigil keep,
Watching for Sítá's welfare thus,
For her dear life depends on us.
Bring me the leaves that lie around,
And spread them here upon the ground,
That we on lowly beds may lie,
And let in talk the night go by.'
