One day, a few days before a year had passed, Kṛṣṇa and Balarāma were maintaining the calves in the forest when They saw some cows grazing on the top of Govardhana Hill. The cows could see down into the valley where the calves were being taken care of by the boys. Suddenly, on sighting the calves, the cows began to run toward them. They leaped downhill with joined front and rear legs. The cows were so melted with affection for the calves that they did not care about the rough path from the top of Govardhana Hill down to the pasturing ground. They approached the calves with their milk bags full of milk, and they raised their tails upwards. When they were coming down the hill, their milk bags were pouring milk on the ground out of intense maternal affection for the calves, although they were not their own calves. These cows had their own calves, and the calves that were grazing beneath Govardhana Hill were larger; they were not expected to drink milk directly from the milk bag but were satisfied with the grass. Yet all the cows came immediately and began to lick their bodies, and the calves also began to suck milk from the milk bags. There appeared to be a great bond of affection between the cows and calves.
When the cows were running down from the top of Govardhana Hill, the men who were taking care of them tried to stop them. Older cows are taken care of by the men, and the calves are taken care of by the boys; and as far as possible, the calves are kept separate from the cows, so that the calves do not drink all the available milk. Therefore the men who were taking care of the cows on the top of Govardhana Hill tried to stop them, but they failed. Baffled by their failure, they were feeling ashamed and angry. They were very unhappy, but when they came down and saw their children taking care of the calves, they all of a sudden became very affectionate toward the children. It was very astonishing. Although the men came down disappointed, baffled and angry, as soon as they saw their own children, their hearts melted with great affection. At once their anger, dissatisfaction and unhappiness disappeared. They began to show paternal love for the children, and with great affection they lifted them in their arms and embraced them. They began to smell their children’s heads and enjoy their company with great happiness. After embracing their children, the men took the cows back to the top of Govardhana Hill. Along the way they began to think of their children, and affectionate tears fell from their eyes.
When Balarāma saw this extraordinary exchange of affection between the cows and the calves and between the fathers and their children—when neither the calves nor the children needed so much care—He began to wonder why this extraordinary thing had happened. He was astonished to see all the residents of Vṛndāvana so affectionate to their own children, exactly as they had been to Kṛṣṇa. Similarly, the cows had grown affectionate to the calves—as much as to Kṛṣṇa. Balarāma therefore concluded that the extraordinary show of affection was something mystical, either performed by the demigods or by some powerful man. Otherwise, how could this wonderful change take place? He concluded that this mystical change must have been caused by Kṛṣṇa, whom Balarāma considered His worshipable Personality of Godhead. He thought, “It was arranged by Kṛṣṇa, and even I could not check its mystic power.” Thus Balarāma understood that all those boys and calves were only expansions of Kṛṣṇa.
