Atharva Veda · Chapter 19.50

adha rātri tṛṣṭadhūmamaśīrṣāṇamahiṃ kṛṇu /
akṣau vṛkasya nirjahyāstena taṃ drupade jahi

ye te rātryanaḍvāhastīkṣṇaśṛṅgāḥ svāśavaḥ /
tebhirno adya pārayāti durgāṇi viśvahā

rātriṃrātrimariṣyantastarema tanvā vayam /
gambhīramaplavā iva na tareyurarātayaḥ

yathā śāmyākaḥ prapatann apavān nānuvidyate /
evā rātri pra pātaya yo asmāmabhyaghāyati

apa stenaṃ vāsayo goajamuta taskaram /
atho yo arvataḥ śiro'bhidhāya ninīṣati

yadadya rātri subhage vibhajantyayo vasu /
yadetadasmān bhojaya yathedanyān upāyasi

uṣase naḥ pari dehi sarvān rātryanāgasaḥ /
uṣā no ahne ā bhajādahastubhyaṃ vibhāvari
