[Peace] comes to freedom from fear. This is what peace is. If you're at peace, then you're not haunted by fears. If you're haunted by any kind of fears, then certainly you cannot say you're at peace, even if your surroundings are peaceful. So, peace is not just a negative state of affairs; it's not just an absence of violence. It means you can enjoy inner serenity because there's an absence not just of violence but of fear — freedom from fear.
