ChU 6.5.4
अन्नमयं हि सोम्य मनः । आपोमयः प्राणः । तेजोमयी वाग् इति । भूय एव मा भगवान् विज्ञापयत्व् इति । तथा सोम्येति होवाच
annamayaṃ hi somya manaḥ | āpomayaḥ prāṇaḥ | tejomayī vāg iti | bhūya eva mā bhagavān vijñāpayatv iti | tathā somyeti hovāca
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
'For truly, my child, mind comes of earth, breath of water, speech of fire.' 'Please, Sir, inform me still more,' said the son. 'Be it so, my child,' the father replied.
