SB 10.1.18
gaur bhutvasru-mukhi khinna
krandanti karunam vibhoh
upasthitantike tasmai
vyasanam samavocata
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Mother earth assumed the form of a cow. Very much distressed, with tears in her eyes, she appeared before Lord Brahma and told him about her misfortune.
