Chanakya says that lust is a man's most powerful enemy. It is such an untreatable disease under the influence of which a man loses his wisdom, as well as his health deteriorates rapidly. Infatuation destroys a man like an enemy. It was infatuation for a son which caused the destructive war of Mahabharata. Similarly, anger is like a wild fire, whose flames repeatedly singe man. It affects man's mind/brain every moment. Chanakya says that knowledge is the best weapon for destroying these disorders.
