6.4.2

sa ha prajāpatirīkṣāṃ cakre hantāsmai pratiṣṭhāṃ kalpayānīti sa striyam̐ sasṛje tām̐ sṛṣṭvādha upāsta tasmātstriyamadha upāsīta sa etaṃ prāñcaṃ grāvāṇamātmana eva samudapārayattenaināmabhyasṛjat

And Pragâpati thought, let me make an abode for him, and he created a woman (Satarûpâ).
Tâm srishtvâdha upâsta, tasmât striyam adha upâsîta. Sa etam prâñkam grâvânam âtmana eva samudapârayat, tenainâm abhyasrigat.
