Ashoka Rock Edict at Kalsi :

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. 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.

The Rock edicts of Khalsi, also Kalsi, are a group of an Indian rock inscriptions written by the Indian Emperor Ashoka around 250 BCE. They contains some of the most important of the Edicts of Ashoka. The inscription in Khalsi contains all the Major Rock Edicts, from 1 to 14. They were discovered in Khalsi, a village of northern India (Dehradun District, Uttarakhand), by Alexander Cunningham about 1850.

The inscription :

The Rock edicts of Khalsi are among the many inscriptions of Ashoka, the first being the Bilingual inscription of Kandahar, written in Greek and in Aramaic, in the year 10 of his reign.The other inscriptions of Ashoka are in Indian language (various forms of Prakrits) with the exception of the Kandahar Greek Edict of Ashoka, and were only published from around 3 to 4 years later, and until 27 years after his coronation.

The Khalsi edicts, placed in North-Western India, were located near the Hellenistic world represented by the Greco-Bactrian Kingdomand its capital Ai Khanoum. The inscriptions were written on a solid quartz rock.  The main face (east face) of the rock contains Edicts 1 to 12 and the first part of Edict 13. On the right side (north face) is the drawing of an elephant with the word in BrahmiGajatama, of uncertain meaning. On the left side (south face) is the continuation of the inscription started on the main face, with the second part of Edict 13 and Edict 14.

This last edict, Edict No.13, is particularly important in that it mentions the main Hellenistic kings of the time, as well as their precise geographical location, suggesting that Ashoka had a very good understanding of the Greek world of the time.It is also this inscription which made it possible to date the reign of Ashoka with a certain precision, between 260 and 230 BCE.This Edict also appears, although in a less well preserved form, in the Girnar inscription, and very damaged in the Mansehra inscription.

Edict 13 refers in particular to contemporary rulers of the Hellenistic period, who had inherited the conquests of Alexander the Great. Its mentions Antiochos II, Ptolemy II, Antigonos II Gonatas, Magas of Cyrene and Alexander II of Epirus.

Now, it is the conquest by the Dharma that the Beloved of the Gods considers as the best conquest. And this one (the conquest by the Dharma) was won here, on the borders, and even 600 leagues from here, where the king Antiochos reigns, and beyond where reign the four kings Ptolemy, Antigonos, Magas and Alexander, likewise in the south, where live the Cholas, the Pandyas, and as far as Tamraparni

— Extract from Edict No.13 :

Some scholars believe that Buddhist communities have emerged in the Hellenistic world following Ashoka's reign, notably in Alexandria (this community being mentioned four centuries later by Clement of Alexandria). Given Ashoka's particularly moral definition of "Dharma" it is possible that he simply wants to say that virtue and piety now exist from the Mediterranean to the south of India. An expansion of Buddhism to the West is unconfirmed historically. In other inscriptions, Ashoka also states that he sent emissaries to the West to transmit medical care and medicinal plants (Major Rock Edict No.2). We do not know what the influence of these emissaries was on the Greek world. 

Relation to Greek philosophy :

According to Valeri Yailenko, the Kineas inscription of Ai Khanoum , dated about 300 BCE, probably influenced the writing of the Edicts of Ashoka a few decades later, around 260 BCE (see also Hellenistic influence on Indian art).The edicts put forward moral rules which are extremely close to the Kinéas inscription of Ai Khanoum, both in terms of content and formulation. Short, aphoristic expressions, the subjects being discussed, the vocabulary itself, are all elements of similarity with the inscription of Kineas.
