Human prosperity flourishes by natural gifts and not by gigantic industrial enterprises. The gigantic industrial enterprises are products of a godless civilization, and they cause the destruction of the noble aims of human life. The more we go on increasing such troublesome industries to squeeze out the vital energy of the human being, the more there will be unrest and dissatisfaction of the people in general, although a few only can live lavishly by exploitation. The natural gifts such as grains and vegetables, fruits, rivers, the hills of jewels and minerals, and the seas full of pearls are supplied by the order of the Supreme, and as He desires, material nature produces them in abundance or restricts them at times. The natural law is that the human being may take advantage of these godly gifts by nature and satisfactorily flourish on them without being captivated by the exploitative motive of lording it over material nature. The more we attempt to exploit material nature according to our whims of enjoyment, the more we shall become entrapped by the reaction of such exploitative attempts. If we have sufficient grains, fruits, vegetables, and herbs, then what is the necessity of running a slaughterhouse and killing poor animals? A man need not kill an animal if he has sufficient grains and vegetables to eat. The flow of river waters fertilizes the fields, and there is more than what we need. Minerals are produced in the hills, and the jewels in the ocean. If the human civilization has sufficient grains, minerals, jewels, water, milk, etc., then why should we hanker after terrible industrial enterprises at the cost of the labor of some unfortunate men? But all these natural gifts are dependent on the mercy of the Lord. What we need, therefore, is to be obedient to the laws of the Lord and achieve the perfection of human life by devotional service.
