Kṛṣṇa is always thinking how to protect the cows and the brāhmaṇas. When Kṛṣṇa appeared on this planet He became a cowherd boy to give protection to the cows. He was tending cows by His personal example. He was taking care of the cows. Therefore go-brāhmaṇa-hitāya ca. The first prayer is that "You are protector of the cows and the brāhmaṇas." Jagad-dhitāya. "You are well-wisher of the whole universe, but Your special interest is to give protection to the cows and the brāhmaṇas." Why that special interest? Because if the human society does not give protection to the cows and does not cultivate the brahminical culture, then it is cats and dogs society.
