Atharva Veda · Chapter 20.25

aśvāvati prathamo goṣu gacchati suprāvīrindra martyastavotibhiḥ /
tamitpṛṇakṣi vasunā bhavīyasā sindhumāpo yathābhito vicetasaḥ

āpo na devīrupa yanti hotriyamavaḥ paśyanti vitataṃ yathā rajaḥ /
prācairdevāsaḥ pra ṇayanti devayuṃ brahmapriyaṃ joṣayante varā iva

adhi dvayoradadhā ukthyaṃ vaco yatasrucā mithunā yā saparyataḥ /
asaṃyatto vrate te kṣeti puṣyati bhadrā śaktiryajamānāya sunvate

ādaṅgirāḥ prathamaṃ dadhire vaya iddhāgnayaḥ śamyā ye sukṛtyayā /
sarvaṃ paṇeḥ samavindanta bhojanamaśvāvantaṃ gomantamā paśuṃ naraḥ

yajñairatharvā prathamaḥ pathastate tataḥ sūryo vratapā vena ājani /
ā gā ājaduśanā kāvyaḥ sacā yamasya jātamamṛtaṃ yajāmahe

barhirvā yatsvapatyāya vṛjyate'rko vā ślokamāghoṣate divi /
grāvā yatra vadati karurukthyastasyedindro abhipitveṣu raṇyati

progrāṃ pītiṃ vṛṣṇa iyarmi satyāṃ prayai sutasya haryaśva tubhyam /
indra dhenābhiriha mādayasva dhībhirviśvābhiḥ śacyā gṛṇānaḥ
