The Stealing of the Boys and Calves by Brahmā
89
The mothers of the boys heard the vibration of their flutes before their entrance, and to receive them, they came out of their homes and embraced them. And out of maternal affection, milk was flowing from their breasts, and they allowed the boys to drink it. However, their offering was not exactly to their boys but to the Supreme Personality of Godhead who had expanded Himself into such boys. This was another chance for all the mothers of Vṛndāvana to feed the Supreme Personality of Godhead with their own milk. Therefore Lord Kṛṣṇa gave not only Yaśodā the chance of feeding Him, but this time He gave the chance to all the elderly  gopīs .
All the boys began to deal with their mothers as usual, and the mothers also, on the approach of evening, began to bathe their respective children, decorate them with  tilaka  and ornaments and give them necessary food after the day's labor. The cows also, who were away in the pasturing ground, returned in the evening and began to call their respective calves. The calves immediately came to their mothers, and the mothers began to lick the bodies of the calves. These relations between the cows and the  gopīs  with their calves and boys remained unchanged, although actually the original calves and boys were not there. Actually the cows' affection for their calves and the elderly  gopīs ' affection for the boys causelessly increased. Their affection increased naturally, even though the calves and boys were not their offspring. Although the cows and elderly  gopīs  of Vṛndāvana had greater affection for Kṛṣṇa than for their own offspring, after this incident, their affection for their offspring increased exactly as it did for Kṛṣṇa. For one year continually, Kṛṣṇa Himself expanded as the calves and cowherd boys and was present in the pasturing ground.
As it is stated in the  Bhagavad-gītā , Kṛṣṇa's expansion is situated in everyone's heart as the Supersoul. Similarly, instead of expanding Himself as the Supersoul, He expanded Himself as a portion of calves and cowherd boys for one continuous year.
One day, when Kṛṣṇa, along with Balarāma, was maintaining the calves in the forest, 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 their calves, the cows began to run towards them. They leaped downhill with joined front and rear legs. The cows were so melted with affection for their calves that they did not care about the rough path from the top of Govardhana Hill down to the pasturing ground. They began to approach 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
