Unless you become Krsna conscious, there is no question of [happiness]. This is a false happiness, that "If I get money, I'll be happy." That is false.

So many men, they have got money. We see practically, the whole European civilization, American civilization, is based on this fundamental idea that "Let us have money and we shall be happy." And nobody is happy. Nobody is happy, [not] a single man.

Very big, big buildings, very nice car, very nice road, but there is no question of happiness. Always restlessness.
