Beloved-of-the-Gods, King Piyadasi, desires that all religions should reside everywhere, for all of them desire self-control and purity of heart. But… - Ashoka

The people of the unconquered territories beyond the borders might think: "What is the king's intentions towards us?" My only intention is that they live without fear of me, that they may trust me and that I may give them happiness, not sorrow. Furthermore, they should understand that the king will forgive those who can be forgiven, and that he wishes to encourage them to practice Dhamma so that they may attain happiness in this world and the next. I am telling you this so that I may discharge the debts I owe, and that in instructing you, that you may know that my vow and my promise will not be broken. Therefore acting in this way, you should perform your duties and assure them (the people beyond the borders) that: "The king is like a father. He feels towards us as he feels towards himself. We are to him like his own children."

Although Ashoka was victorious in this horrific and gruesome war, he felt remorse for all the suffering he had caused and hence turned to Buddhism. He wrote in his Edict Thirteen that: The Kalingas were conquered by His Sacred Majesty the King when he had been consecrated for eight years. One hundred and fifty thousand persons were thence carried away captive, and one hundred thousand were there slain, and many times that number perished. Directly after the annexation of the Kalingas, began his Sacred Majesty's zealous protection of Dharma, his love of Dharma, and his giving instruction in that. Thus arose His Sacred Majesty's remorse for having conquered the Kalingas, because the conquest of a country previously unconquered involves the slaughter, death, and carrying away captive of the people. That is a matter of profound sorrow and regret to His Sacred Majesty.

Beloved-of-the-Gods, King Piyadasi, honors both ascetics and the householders of all religions, and he honors them with gifts and honors of various kinds. But Beloved-of-the-Gods, King Piyadasi, does not value gifts and honors as much as he values this — that there should be growth in the essentials of all religions. Growth in essentials can be done in different ways, but all of them have as their root restraint in speech, that is, not praising one's own religion, or condemning the religion of others without good cause. And if there is cause for criticism, it should be done in a mild way. But it is better to honor other religions for this reason. By so doing, one's own religion benefits, and so do other religions, while doing otherwise harms one's own religion and the religions of others. Whoever praises his own religion, due to excessive devotion, and condemns others with the thought "Let me glorify my own religion," only harms his own religion. Therefore contact (between religions) is good. One should listen to and respect the doctrines professed by others. Beloved-of-the-Gods, King Piyadasi, desires that all should be well-learned in the good doctrines of other religions.
