2.9.6

sṛjyamāmāḥ prajā naiva vivarddhante yadā yadā /
dvidhā kṛtvātmano dehamarddhena puruṣo 'bhavat /
arddhena nārī tasyāṃ sa sasṛje vividhāḥ prajāḥ //

When the creatures being created did not multiply at all,
dividing his own body in two, by one half he became male,
and by the other half female; upon her he brought forth diverse progeny.
