So you all, boys and girls, those who have come from America, I am very much thankful to you. But don’t be less serious. Be very serious. And another thing I’ll request especially to the Americans, that America has got good potentiality to save the world, so if you preach very nicely in your country… And not all of them will be interested, but if a section of men in your country, you can turn them to become Krsna conscious, it will be great benefit to the whole world. But the aim is the same, punar-janma-jayaya: to gain victory over this process of birth, death and old age. This is not fiction; this is fact. People are not serious. But you can teach your people; otherwise, the whole human society is at risk. They are like animals.
