It was said that the first cow appeared during the Samudra Manthan, churning of the sea in the Bhagavata Purana in the Mahabharata and in the Vishnu Purana. Lord Krishna grew up herding cows, and playing his flute to the Gopis (milkmaids). His names “Govinda” and “Gopala” means, friend and protector of cows. Even Lord Shiva’s Bull Nandi is the sacred bull. Nandi is worshipped in his own right as the bearer of truth and righteousness.
