विदुर उवाच
कस्माद्दधार गोरूपं धरित्री बहुरूपिणी ।
यां दुदोह पृथुस्तत्र को वत्सो दोहनं च किम् ॥ ३ ॥
vidurah uvaca-Vidura inquired; kasmat-why; dadhara-took; go-rupam-the shape of a cow; dharitri-the earth; bahu-rupini-who has many other forms; yam-whom; dudoha-milked; prthuh-King Prthu; tatra-there; kah-who; vatsah-the calf; dohanam-the milking pot; ca-also; kim-what.
Vidura inquired from the great sage Maitreya: My dear brahmana, since mother earth can appear in different shapes, why did she take the shape of a cow? And when King Prthu milked her, who became the calf, and what was the milking pot?
