What does ashokan inscription tell us …

The Asokan inscriptions give us a lot of information about the Mauryas. Asoka was one of the greatest Mauryan kings who engraved several of his orders and doctrines on rocks and stones.
a. Most of the Asokan inscriptions are written in Pali and Prakrit. Because these inscriptions were engraved for the common people, it indicates that these were the local languages of the people. In northwestern parts of the subcontinent, the inscriptions were in kharosthi script as the Greeks had ruled this region.
b. Asoka in one of his inscriptions has laid down that earlier rulers had no arrangements to receive reports.
c. The Asokan inscriptions shed light on the policy of dhamma followed by Asoka. According to the Asokan principle of dhamma, elders should be respected, slaves should be treated kindly and religious tolerance should be practised. These highlight the liberal principles of the Mauryan ruler.
d. One of the Asokan inscriptions also narrates the pain of the king after the Kalinga War in which thousands of soldiers were killed. After the war, the king embraced Buddhism.
