Ramayana 2.82.18

यदि त्वार्यं न शक्ष्यामि विनिवर्तयितुं वनात्।वने तत्रैव वत्स्यामि यथाऽर्यो लक्ष्मणस्तथा।।।।

yadi tv āryaṃ na śakṣyāmi vinivartayituṃ vanāt | vane tatraiva vatsyāmi yathāryo lakṣmaṇas tathā ||

If I cannot bring my noble brother back from the forest, then I shall dwell there in the woods themselves—just as the noble Lakṣmaṇa does.
