Pṛthivī-dohaṇa (The Milking of the Earth) and the Praise of King Pṛthu
इति श्रीब्रह्माण्डे महापुराणे वायुप्रोक्ते पूर्वभागे द्वितीये ऽनुषङ्ग पादे शेषमन्वन्तराश्यानं पृथिवीदोहनं च नाम षट्त्रिंशत्तमो ऽध्यायः सूत उवाच आसीदिह समुद्रान्ता वसुधेति यथा श्रुतम् / वसु धत्ते यतस्तस्माद्वसुधा सेति गीयते
iti śrībrahmāṇḍe mahāpurāṇe vāyuprokte pūrvabhāge dvitīye 'nuṣaṅga pāde śeṣamanvantarāśyānaṃ pṛthivīdohanaṃ ca nāma ṣaṭtriṃśattamo 'dhyāyaḥ sūta uvāca āsīdiha samudrāntā vasudheti yathā śrutam / vasu dhatte yatastasmādvasudhā seti gīyate
Thus, in the Śrī Brahmāṇḍa Mahāpurāṇa, in the former section spoken by Vāyu, in the second Anuṣaṅga-pāda, is the thirty-sixth chapter called “The Account of the Remaining Manvantaras and the Milking of the Earth.” Sūta said: as has been heard, this Vasudhā extended to the ocean’s bounds; because she bears the vasus—treasures and wealth—she is sung of as “Vasudhā.”
