One day, while tending the cows, Kṛṣṇa, Balarāma and the cowherd boys became engrossed in playing hide-and-go-seek. Some of the boys took the role of sheep, some the role of thieves, and others shepherds. The shepherds would search for the sheep when the thieves stole them. Taking advantage of this game, a demon named Vyoma, sent by Kaṁsa, dressed himself like a cowherd boy and joined the band of “thieves.” He abducted a few cowherd boys at a time and threw them into a mountain cave, keeping them there by blocking the entrance with a boulder. Gradually Vyomāsura abducted all but four or five cowherd boys. When Kṛṣṇa saw what the demon was doing, He ran after him, grabbed him and killed him just as one would kill a sacrificial animal.
