Pṛthivī-dohaṇa (The Milking of the Earth) and the Praise of King Pṛthu
ततो ऽभ्युपगमाद्राज्ञः पृथोर्वैन्यस्य धीमतः / दुहितृत्वमनुप्राप्ता पृथिवी पठ्यते ततः
tato 'bhyupagamādrājñaḥ pṛthorvainyasya dhīmataḥ / duhitṛtvamanuprāptā pṛthivī paṭhyate tataḥ
Then, because the wise king Pṛthu Vainya accepted her, the Earth attained the status of a daughter; therefore from that time she is recited as “Pṛthivī.”
