Atharva Veda 4.14

ajo hy agner ajaniṣṭa śokāt so apaśyajjanitāram agre tena devā devatām agrā āyan tena rohān ruruhur medhyāsaḥ

With the sacrifice of a goat

Since the goat has been born from the heat of Agni (the fire), it saw [its] generator in the beginning; by it the gods in the beginnings attained (i) [their] godhead; by (with?) it the sacrificial ones (médhya) ascended the ascents (róha).

kramadhvam agninā nākam ukhyān hasteṣu bibhrataḥ divas pṛṣṭhaṃ svar gatvā miśrā devebhir ādhvam

Stride ye with the fire to the firmament (nā́ka), bearing in your hands vessel-[fires] (úkhya); having gone to the back of the sky, to the heaven (svàr), sit ye mingled with the gods.

pṛṣṭhāt pṛthivyā aham antarikṣam āruham antarikṣād divam āruham divo nākasya pṛṣṭhāt svar jyotir agām aham

From the back of earth I have ascended to the atmosphere; from the atmosphere I have ascended to the sky; from the back of the sky, of the firmament (nā́ka), I have gone to heaven (svàr), to light.

svar yanto nāpekṣanta ā dyāṃ rohanti rodasī yajñaṃ ye viśvatodhāraṃ suvidvāṃso vitenire

Going to heaven (svàr) they look not away; they ascend to the sky, the two firmaments (ródasī)—they who, well-knowing, have extended the everywhere-streaming sacrifice.

agne prehi prathamo devatānāṃ cakṣur devānām uta mānuṣānām iyakṣamāṇā bhṛgubhiḥ sajoṣāḥ svar yantu yajamānāḥ svasti

O Agni, go forth first of the divinities, eye of gods and of human beings (mā́nuṣa)—pressing on (? íyakṣa-) in unison with the Bhṛgus, let the sacrificers go to heaven (svàr), to well-being.

ajam anajmi payasā ghṛtena divyaṃ suparṇaṃ payasaṃ bṛhantam tena geṣma sukṛtasya lokaṃ svar ārohanto abhi nākam uttamam

With milk, with ghee, I anoint the goat, the heavenly eagle, milky, great; by it may we go to the world of the well-done, ascending the heaven (svàr), unto the highest firmament (nā́ka).

pañcaudanaṃ pañcabhir aṅgulibhir darvyoddhara pañcadhaitam odanam prācyāṃ diśi śiro ajasya dhehi dakṣiṇāyāṃ diśi dakṣiṇaṃ dhehi pārśvam

Accompanied by five rice-messes (-odaná), by the five fingers, with the spoon, take thou up five-fold that rice-mess. In the eastern quarter set thou the head of the goat; in the southern (dákṣiṇa) quarter set his right (dákṣiṇa) side.

pratīcyāṃ diśi bhasadam asya dhehy uttarasyāṃ diśy uttaraṃ dhehi pārśvam ūrdhvāyāṃ diśy ajasyānūkaṃ dhehi diśi dhruvāyāṃ dhehi pājasyam antarikṣe madhyato madhyam asya

In the western quarter set his rump (bhasád); in the northern (úttara) quarter set his other (úttara) side; in the upward quarter set the goat's back-bone; in the fixed quarter set his belly (? pājasyà); midway in the atmosphere his middle.

śṛtam ajaṃ śṛtayā prorṇuhi tvacā sarvair aṅgaiḥ saṃbhṛtaṃ viśvarūpam sa ut tiṣṭheto abhi nākam uttamaṃ padbhiś caturbhiḥ prati tiṣṭha dikṣu

Do thou envelop with cooked skin the cooked goat, brought together with all his limbs, all-formed. Do thou rise up from here unto the highest firmament (nā́ka); with thy four feet stand firm in the quarters.
