We must destroy lobha or covetousness and moha or undue attachment as these are our creation. We must modify anger and passion as these are God 's creation. World is rushing towards destruction with headlong speed as people are misusing the powers given by God and creating mess. Lord Rama' s war against Rawan, Noah's flood and battle of Mahabharata are some instances . We should be courageous and not go against nature or environment.
