BG Chap 16 - The demons destroy the world
Following such philosophies as explained above, the demons, who are lost to themselves and unintelligent, engage in unbeneficial, violent actions meant to destroy the world. Taking support of their philosophies, the foolish people, with worthless opinions, devoid of understanding ātmā as distinct from the body, engage in violent actions and destroy the world. Since the world is an illusion and is devoid of any God in control, they trash the world. By causing the world to deviate from the principles of spiritual life, they are the enemies of the world, and thus they exert their influence for the world’s destruction. The materialists, who have no concept of God, think that they are advancing. But according to Bhagavad-gītā, they are unintelligent and devoid of all sense. They try to enjoy this material world to the utmost limit and therefore always engage in inventing something for sense gratification. Such materialistic inventions are considered to be advancement of human civilization, but the result is that people grow more and more violent and more and more cruel, cruel to animals and cruel to other human beings. They engage in ugra-karma or painful, distressful, horrible activities such as animal killing, producing nuclear weapons, creating breweries, cigarette factories, and nightclubs and engaging in large scale industrial development and trade.
