PURPORT

The four-headed Brahma perceived the opulence of Dvaraka-dhama where Krsna was staying, and although there were Brahmas present having ten to ten million heads, and also many Lord Sivas were also assembled, only the four-headed Brahma of this universe could see all of them. By the inconceivable potency of Krsna, the others could not see one another. Althouth all the Brahmas and Sivas were assembled together, due to Krsna's energy, they could not meet or talk among themselves individually.
