When Aghasura died, the demigods offered prayers, threw flowers, and beat drums. Hearing the commotion, Lord Brahma arrived on the scene. At that time Brahma kidnapped the children children, an offense unbecoming of a demigod. Krishna was unhappy because due to Brahma's misdeed, because He would have to go back to the village alone. Instead, He decided to expand himself into substitute boys and calves that looked exactly like the originals, and he returned to the village with them. No one could tell the difference, but families showed increased spontaneous affection to their sons (who were actually expansions of God). Balarama, Krishna's brother, noticed the parents' behavior and asked Krishna what was going on. Krishna explained how Lord Brahma had kidnapped the real boys and calves.
Brahma made a mistake in trying to test Krishna's power. Life went on like this for a year before Brahma returned. Brahma's time passes much more quickly, so it seemed to him only a moment. However, when he returned he was shocked to see the boys and calves playing with Krishna, as though nothing had happened. Krishna knew Brahma was perplexed so He transformed all the boys and calves into four-armed Vishnu forms. Brahma heard music and saw many Brahmas, Shivas, demigods and jivas (souls) singing God's names and dancing. Brahma's mind opened at first to the vision, but then he became bewildered, so Krishna ended the dazzling scene.
When Brahma woke up, he realized that he was face to face with Krishna the Supreme Personality of Godhead, who was enacting His eternal pastimes as a cowherd boy in the spiritual land of Vrindavana. Brahma immediately got down from his swan-carrier and fell prostate at Krishna's feet to beg forgiveness. After offering glorious prayers and penance for his behavior, Brahma circumambulated Krishna three times and returned to his planet.
Exactly one year before, Krishna had left his friends eating lunch on the bank of the Jamuna River. When he returned, they had just begun the meal, and thought Krishna had only been gone for a second. None of the boys realized that a whole year had gone by and that they had been kidnapped, asleep in a cave. When the children returned to their homes and told their parents about the aghasura demon, the demon's corpse had decomposed so the parents thought it was just a wild tale from the children's imagination.
