मेढ्रं तस्य विनिर्भिन्नं स्वधिष्ण्यं क ।
उपाविशत्रेतसांशेन येनासाव् आनन्दं प्रतिपद्यते ॥ १९ ॥
medhram tasya vinirbhinnam
upavisat retasamsena yenasav
medhram-genitals; tasya-of the gigantic form; vinirbhinnam-being separated; sva-dhisnyam-own position; kah-Brahma, the original living creature; upavisat-entered; retasa amsena-with the part of the semina; yena-by which; asau-the living entity; anandam-sex pleasure; pratipadyate-experiences.
When the genitals of the gigantic form separately became manifest, then Prajapati, the original living creature, entered into them with his partial semina, and thus the living entities can enjoy sex pleasure.
