The defect of the modern civilization is that everyone is earning money undoubtedly in large volumes, but he does not know how to spend. He is spending simply for sense gratification and the last word of sense gratification is sex, therefore all money is being spent up for intoxication and sexual life, nudey dance, nudey theater, in so many ways. That means they are spoiling their human source of energy. Next point, one should be so trained up that within the heart he will be freed from all material attraction, but so long the body is there, to keep the body and soul together, he has to work like ordinary man. Next point, the society, friendship and love of material existence may be accepted without any attraction, and whatever the so-called society, friendship and love wants to take service from Krishna Consciousness or God consciousness movement, one should simply say, yes, it is very nice, but actually he should give more importance for spiritual advancement of life.
