Term "dhamma" refers to the ethical and moral principles advocated by Emperor Ashoka. After the Kalinga War, which was a brutal and bloody conflict, Ashoka underwent a profound change of heart and embraced Buddhism. He then dedicated himself to the promotion of peace, non-violence, and moral conduct.

Ashoka's concept of "dhamma" was not limited to Buddhist principles; it was a broader term that encompassed values and virtues applicable to people of all religious backgrounds. Ashoka inscribed his edicts on pillars and rocks throughout the Mauryan Empire, spreading the message of dhamma to his subjects. The principles of dhamma included compassion, tolerance, truthfulness, and respect for all living beings.

The promotion of dhamma was a significant aspect of Ashoka's rule and had a lasting impact on the Mauryan Empire and its governance. It reflected the emperor's commitment to creating a just and humane society based on ethical values.
