Any civilization devoid of God consciousness or Krishna Consciousness, is no civilization at all. It is simply a polished type of animal society. This is the first point. So at the present moment, the modern civilization on the basis of so-called scientific knowledge and economic development is trying to avoid God consciousness, or Krishna Consciousness - that is the defect of the modern civilization. Therefore, in spite of all advancement it is zero. So zero has no value. And millions of zeros put together does not make any value. But one is put on the left side of the zero, it increases the value. Then one zero becomes 10, two zero becomes 100, three zero becomes 1000, so it is very nice. This point should be clearly discussed, that without God consciousness, Krishna Consciousness, any attempt of human civilization so-called philosophical or political or economical or labor, they are all zeros.
