PrU 1.4
तस्मै स होवाच । प्रजाकामो वै प्रजापतिः । स तपो ऽतप्यत । स तपस् तप्त्वा स मिथुनम् उत्पादयते रयिं च प्राणं चेति । एतौ मे बहुधाः प्रजाः करिष्यत इति
tasmai sa hovāca | prajākāmo vai prajāpatiḥ | sa tapo 'tapyata | sa tapas taptvā sa mithunam utpādayate rayiṃ ca prāṇaṃ ceti | etau me bahudhāḥ prajāḥ kariṣyata iti
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
He replied: "Pragâpati (the lord of creatures) was desirous of creatures (pragâh). He performed penance, and having performed penance, he produces a pair, matter (rayi) and spirit (prâna), thinking that they together should produce creatures for him in many ways.
