śākambharīti vikhyātiṃ tadā yāsyāmyahaṃ bhuvi /
tatraiva ca vadhiṣyāmi durgamākhyaṃ mahāsuram /
durgā devīti vikhyātaṃ tanme nāma bhaviṣyati //

Next, O ye gods, I shall support[25] the whole world with the life-sustaining vegetables, which shall grow out of my own body, during a period of heavy rain. I shall gain fame on the earth then as Śākambharī;[26] and in that very period I shall slay the great Asura named Durgama.
