The invasion of Kalinga was a big milestone in the history of Magadha, and of India. It had influential consequences. It had an incredible influence on the personal life and policy of Asoka. The despair and casualty which he had inflicted upon the people of Kalinga filled his heart with deep sorrow and regret. The cry of the wives and women of the deads, the tears of the children, the terrifying sufferings of the dying men, all had changed his heart and mind. He found his consolation in Buddhism. He was repenting for his deeds. He embraced Buddhism and took the vow of inculcating ‘Dhamma’ to all men throughout his life. King Asoka left behind the policy of Digvijay and adopted the policy of Dhamma-Vijaya. There were significant changes in state policy. It ended the policy of Magadhan imperialism. Asoka ended the age-old policy of aggression and conquest of the Magadhan Kings. A new policy of Peace and non-violence began to be adopted in the realm of inter-state relation. The call of Dharma, where all are equal and all feels for all began to flourish. The blood-thirsty tyrant became a lover of mankind who preached non-violence.
