Pṛthivī-dohaṇa (The Milking of the Earth) and the Praise of King Pṛthu
मधुकैटभयोः पूर्वं मेदसा संपरिप्लुता / तेनेयं मेदिनीत्युक्ता निरुक्त्या ब्रह्मवादिभिः
madhukaiṭabhayoḥ pūrvaṃ medasā saṃpariplutā / teneyaṃ medinītyuktā niruktyā brahmavādibhiḥ
Before the time of Madhu and Kaiṭabha, this earth was wholly flooded with medas—fatness; therefore the brahmavādins, by nirukti (sacred etymology), spoke of her as “Medinī.”
