The greatness of Ashoka is not only due to his territorial expansion, but for his moral greatness and the practical ethics which he propagated. The Kalinga war was a turning point in the life of Ashoka. Seeing the extent of the loss of human li fe and bloodshed, Ashoka was fi 1 led with sorrow and vowed to stop ‘Digvijaya or Bhcri Ghosha (Beating of war drums) and to take up ‘Dharmavijaya’ (Winning the hearts of the people). He declared “The Chief conquest is the conquest by right path and love and not by might and sin”. The Bhabru edict clearly indicates Ashoka’s faith in Buddha, Sangha and Dharmas.

The intention of Ashoka was to spread Buddhism not only in India but also outside India. 

He took many measures for the same. They were:

• He visited the holy places from the life of Buddha such as Lumbini, Kapilavastu. Gaya, Saranath and arranged discourses on religion. 
• He constructed a large number of monasteries all over the Empire and gave liberal grants for such institutions. 
• He spread the doctrines of Buddha by engraving them on rocks, pillars and on the walls of the caves throughout his Empire. 
• Ashoka appointed officers called Dharmamahamathras, Yukthas and Rajjukas to spread Buddhism among people. He also appointed Sthree Adhyaksha Mahamalras to take care of women and bring religious awareness among them. 
• He organised the 3rd Buddhist Council at Pataliputra which was presided by Moggaliputra Tissa in 250 BCE. The purpose was to settle the differences among the Buddhists.
• Ashoka sent missionaries to preach Buddhism in Afghanisthan, Burma, Srilanka and Europe. He deputed his son Mahendra and daughter Sanghamithra to Srilanka with a Bodhi Sapling as a symbol of peace. 
• He undertook many welfare activities like digging of wells, building rest houses, planting of fruit-bearing trees etc., He constructed hospitals for men and animals. He made arrangements to feed the poor and physically disabled persons. His aim was “Service and Sacrifice”.

Ashoka believed that a moral life was the pre-requisite for a happy life. He laid emphasis on simple living, high thinking and a good moral life. On account of his extensive propagation, Buddism became a religion of the masses in India and it also spread to Nepal, Tibet, China, Japan, Burma and many Southeast Asian countries and thus became a world religion during his period.
