→ Consequence: Converted to Buddhism (under teacher Upagupta); gave up conquest of war (Bherighosha) for conquest of Dhamma (Dhammaghosha)
→ Kalinga = modern Odisha

Dhamma Policy

Ashoka's Dhamma (Pali for Dharma) was NOT just Buddhism — it was a universal secular code of ethics:

→ Respect for all religions and sects
→ Non-violence (reduction of animal slaughter; no eating of meat in royal kitchens)
→ Obedience to parents, elders, teachers
→ Truthfulness and compassion
→ Lack of extravagance and cruelty

Spread through: Dhamma Mahamattas — special officials touring the empire to spread Dhamma; inspection tours by Ashoka himself
