Yagyavalkya has said about the wars, 'One who says that he is yours, an impotent, one who has no arrows, one who is affectious, one who has turned back from a war, and those who are witnessing a war should not be killed. This Shlokas has suffixed 'etc' to the list of these forbidden people, therefore, a horse, a warrior without a chariot driver, one with the folded hands, one with untied hair, one who has given away a fight, one sitting on a tree, one sitting on a bare ground, one drinking water, one eating food, one without protective shield, a bard, a messenger, a cow, a brahmin, a she elephant, a chariot and a king should not be killed by a king. It is preached in Gautam, Shankha and other Smritis. Knowers of virtuous living and scriptures have preached that the war is the last alternative to be chosen as a solution: Vidur Niti says that an arrow released from the hands may or may not kill a person, but the intellect released from the brain of an intelligent one kills the king with his entire kingdom.' And therefore, Manu Maharaj suggests reprimand as a first step of punishing, then in order comes oral punishment, monitory punishment, and in last is beheading. But has very clearly said that it is most proper to punish wickeds for founding and strengthening religious duties in the state. For this, there is one statement of king Ashwapati in Chhandogya Upanishada: In my kingdom there is no thief, no miser, no alcoholic, no body is without of Agnihotra, nobody is an ignorant and nobody is a debauch, then how could there be any debauch women?' Kamandak Niti Shastra has said, 'It is not proper to exempt from punishment a sinner, if he be a brother, a son, an elder, a father-in-law or a maternal uncle, though he has fallen from the religion of course, there are some situations where such punishments are exempted. Bhagwat says, 'Oh wife of the brave one! Those who are non-brahmin and have committed a sin, I punish them. In all three Lokas, I don't see any body free from grief and living happily except of devotees of God.' I hold canon of punishment in all seven islands excepting lineage of Brahmins and devotees of Bhagwan.' 'There should be no impact of royal majesty on a brahmin lineage adorned with endurance, penance and knowledge and Parmatma (supreme soul) is their deity.' Bharat says that, accordingly the force of Kaliyug gives a way to the force of virtues of a king. King is the cause of destiny or time or the destiny or time is the cause of a king or the polity. There should be no doubt in it that the king is the cause of time. 'If a king lives religiously, his subjects live a religious life. And if acts a king sinfully, his subject becomes sinful. If acts moderately, subjects too act in a moderate way, subjects follow their king; as a king would be, the subjects would be like that.' It is the wisdom of Chanakya.
