Poem: “No turban on the head and no coat on the body; who is he and in which village does he live? He wears a torn dhoti and a tattered cloth, and has no shoes on his feet. A frail Brahmin stands at the door; the delight of the earth looks on in surprise. He asks for the abode of the Compassionate One and tells his own name: Sudama.” Question: Which word used in the poem is a synonym of 'पृथ्वी'?
