PURPORT

Although Brahma was already entangled in bewilderment, he wanted to show his power to the cowherd boys; but after he took away the boys and their calves and returned to his abode, Krsna created further astonishment for Brahma, and for the mothers of the boys, by establishing the lunch pastimes in the forest again and replacing all the calves and boys, just as they had appeared before. According to the Vedas, ekam bahu syam: the Personality of Godhead can become many, many millions upon millions of calves and cowherd boys, as He did to bewilder Brahma more and more.
