Maybe a little idealistic, but 2 or 3 of these "duties" would be nice to see in any of the current slave lords.
The basic framework of Buddhist ethics for rulers is set out
in the "Ten Duties of the King" (dasa-raja-dhamma):
1. Dana -- liberality, generosity, charity. The ruler should
not have craving and attachment for wealth and property, but
should give it away for the welfare of the people.
2. Sila -- a high and moral character. He should never
destroy life, cheat, steal and exploit others, commit
adultery, utter falsehood, or take intoxicating drinks.
3. Pariccaga -- sacrificing everything for the good of the
people. He must be prepared to give up all personal comfort,
name and fame, and even his life, in the interest of the
people.
4. Ajjava -- honesty and integrity. He must be free from fear
and favour in the discharge of his duties, must be sincere in
his intentions, and must not deceive the public.
5. Maddava -- kindness and gentleness. He must possess a
genial temperament.
6. Tapa -- austerity of habits. He must lead a simple life,
and should not indulge in a life of luxury. He must have
self-control.
7. Akkodha -- freedom from envy, ill-will, enmity. He should
bear no grudge against anybody.
8. Avihimsa -- non-violence, which means not only that he
should harm nobody, but that he should try to promote peace by
avoiding and preventing war, and everything which involves
violence and destruction of life.
9. Khanti -- patience, forbearance, tolerance, understanding.
He must be able to bear hardships, difficulties and insults
without losing his temper.
10. Avirodha -- non-opposition, non-obstruction, that is to
say that he should not oppose the will of the people, should
not obstruct any measures that are conducive to the welfare of
the people. In other words he should rule in harmony with the
people.
