PrU 4.3
प्राणाग्नय एवैतस्मिन् पुरे जाग्रति । गार्हपत्यो ह वा एषो ऽपानः । व्यानो ऽन्वाहार्यपचनः । यद् गार्हपत्यात् प्रणीयते प्रणयनात् । आहवनीयः प्राणः
prāṇāgnaya evaitasmin pure jāgrati | gārhapatyo ha vā eṣo 'pānaḥ | vyāno 'nvāhāryapacanaḥ | yad gārhapatyāt praṇīyate praṇayanāt | āhavanīyaḥ prāṇaḥ
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
The fires of the prânas are, as it were, awake in that town (the body). The Apâna is the Gârhapatya fire, the Vyâna the Anvâhâryapakana fire; and because it is taken out of the Gârhapatya fire, which is fire for taking out, therefore the Prâna is the Âhavanlya fire.
