When king Devanampriya Priyadarshi had been anointed eight years, the country of the Kalingas was conquered by him. One Hundred and fifty thousand in number were the men who were deported thence;One hundred and thousand in numbers were those who were slain there; and many times as many those who died.
After that, now that the country of the Kalingas has been taken, Devanampriya is devoted to the pursuit of Dhamma, the love of Dhamma, and to instructing the people in Dhama. This is the repentance of Devanamprira an account of his conquest of the country of the Kalingas. For the slaughter, death, and deportation of people that take place in the course of conquering an unconquered country is considered very painful and deplorable by Devanampriya.
But the following is considered even more deplorable than this by Devanampriya- that Brahmanas and Shramanas, members of other sects or householders who are living there, and who practice obedience and firm devotion to superior persons, obedience to mother and father, obedience to elderd, proper courtesy to friends, acquaintances, companions, and relatives, to slave and servants-all these suffer injury or slaughter or deportation of their loved ones. And if misfortune befalls the friends, acquaintances, companions, and relatives of persons who are full of devotion towards them, even though they themselves be well provided for, this misfortune too becomes an injury to their own selves. This is shared by all and is considered deplorable be Devanampriya.
there is no place where men are not indeed attached to some sect. therefore, even the hundredth part or the thousands part of all those people who were slain, who died, and who were deported at that time in Kalinga, would now be considered very deplorable by Devanampriya. And Devanampriya thinks that even to one who should wrong him, what can be forgiven is to be forgiven. And even the inhabitanta of the forests which are included in the dominion of Devanampriya, even those he pacifies and conciliates. And they are told to the power to punish them which Devanampriya possesses in spite of his repentance, in order that they may be ashamed of their crimes and may not be killed. For Devanampriya desires towards all beings abstention from hurting, self control and impartiality in case of violence. And this conquest is considered the greatest one by Devanampriya- the conquest by Dhamma.
