“O My Lord, Supreme God of the brahmanas, You are the well-wisher of the cows and the brähmanas. Dear Lord Krishna, You are the well-wisher of the entire human society and world and the beloved of the cows, who You love so much. Please accept my humble obeisances.” (Vishnu Purana 1.19.65)
"After grazing the cows, when Lord Krishna returns in the evening at the time of cowdust, his face is charming like a lotus. The dark-hued Krishna's popular titles Govind and Gopal reveal the grand majesty of cows. "
