If people become Krsna conscious, the whole world will become beautiful, Vaikuntha, without any anxiety. That is possible. Because that is nature’s law. Just like if you become criminal, the state police force will always harass you. You cannot get out of it. He’ll harass you. But that is expensive job for the government. Because it requires extra police, extra management, extra everything. But if the people become honest, God conscious, so many expenditure will be reduced. And money will be saved for spreading Krsna consciousness or for Krsna’s service. Then the whole world will become exactly as it was in the Prthu Maharaja’s day.
