Explanation:

The site of Asoka's inscriptions at Kalsi the only place in north India where the great Mauryan emperor has inscribed the set of the fourteen rock edicts (res). The language of these edicts is Pali and the script Brahmi which reflect Asoka's humane approach in his internal administration, his fatherly concern for the moral and spiritual welfare of his subjects, and his commitment to non-violence and abandonment of warfare. For this Asoka proclaimed certain restrictive and prescriptive policies. The essence of the restrictive policies are restraint in worldly amusement, in gratuitous slaughter or non destruction of animals, in participating in despicable and useless beliefs and practices, and in glorification of one's own faith. That of prescriptive ones: self-control, purity of mind, gratitude, and firm attachment service to parents and ascetics, alms to brahmins and sramanas (ascetics), seemly behaviour towards friends, relatives, acquaintances, servants and slaves, concordance in religious matters.
To implement his policies Asoka put restraint in killing animals for the royal kitchen, established hospitals and planted medicinal herbs for both human beings and animals. He did not only within his empire but also in the neighbouring kingdoms: Chodas, Pamdiyas, Satiyaputras, Kerlaputras upto tambapamni (srilanka) in the south, and of hellenic kings in the west. He appointed dhamma mahamatra-s (overseers of the sacred law) for the promotion of righteous conduct, and replacing sound of trumpet signalling war used sound of dhamma (righteousness) whereby he claims to have gained dhamma vijay (victory by means of righteousness) even in the kingdoms of his contemporary hellenic kings, namely, antiochus (i) theos of Sriya, Ptolemy (ii) Philadelphia of Egypt, Antigonus Gonatas of Macedonia, magas of Cyrene and Alexender of epirus. Thus, these inscriptions bear testimony to the facts that what Asoka preached also practiced. That is why he is acclaimed as one of the greatest emperors in the world.
