PURPORT

After Brahma stole the original cowherd boys and calves, Krsna expanded Himself to become the boys and calves again. Therefore, because the boys were actually Krsna's expansions, the cowherd men were especially attracted to them. At first the cowherd men, who were on top of the hill, were angry, but because of Krsna the boys were extremely attractive, and therefore the cowherd men immediately came down from the hill with special affection.
