I felt myself dwarfed standing next to the majestic Emperor Asoka. Asoka led two lives, one as a ruthless conqueror and the other as a compassionate ruler. The man I stood beside was the one who had just returned from conquest. But victory had been obtained at a heavy cost: the battle of Kalinga claimed the lives of at least 300,000 people and an equal number were wounded. I saw everyone looking at Asoka who fell on his knees and removed his armour and crown. His face was pale, reflecting the death surrounding him. He looked at the sky. He saw the bright cool moon shining and God's grace pouring down on mother earth. And he looked down at the horror he had created, making blood flow everywhere. In that moment of beauty and horror - the silver moonlight and the suffering and pain on the ground, when Nature itself seemed to speak out against what he had wrought, Ahimsa Dharma was born. Emperor Asoka embraced God's command to propagate love for human beings through this doctrine.

Asoka removed his armour and crown as :

he felt the pain and suffering caused by the war.
