Monks, who are professional practitioners of the Dhamma are expected to be completely pacifist.
"Well then, Punna. Now that I have instructed you with a brief
instruction, in which country are you going to live?"
"Lord, there is a country called Sunaparanta. I am going to live
there."
"Punna, the Sunaparanta people are fierce. They are rough. If they
insult and ridicule you, what will you think?"
"If they insult and ridicule me, I will think, 'These Sunaparanta
people are civilized, very civilized, in that they don't hit me with
their hands.' That is what I will think, O Blessed One. That is what I
will think, O One Well-gone."
"But if they hit you with their hands, what will you think?"
"...I will think, 'These Sunaparanta people are civilized, very
civilized, in that they don't hit me with a clod.'..."
"But if they hit you with a clod...?"
"...I will think, 'These Sunaparanta people are civilized, very
civilized, in that they don't hit me with a stick.'..."
"But if they hit you with a stick...?"
"...I will think, 'These Sunaparanta people are civilized, very
civilized, in that they don't hit me with a knife.'..."
"But if they hit you with a knife...?"
"...I will think, 'These Sunaparanta people are civilized, very
civilized, in that they don't take my life with a sharp knife.'..."
"But if they take your life with a sharp knife...?"
"If they take my life with a sharp knife, I will think, 'There are
disciples of the Blessed One who — horrified, humiliated, and
disgusted by the body and by life — have sought for an assassin, but
here I have met my assassin without searching for him.' 1 That is
what I will think, O Blessed One. That is what I will think, O One
Well-gone."
"Good, Punna, very good. Possessing such calm and self-control you are
fit to dwell among the Sunaparantans. Now it is time to do as you see
fit."
Then Ven. Punna, delighting and rejoicing in the Blessed One's words,
rising from his seat, bowed down to the Blessed One and left, keeping
him on his right side. Setting his dwelling in order and taking his
robe and bowl, he set out for the Sunaparanta country and, after
wandering stage by stage, he arrived there. There he lived. During
that Rains retreat he established 500 male and 500 female lay
followers in the practice, while he realized the three knowledges and
then attained total (final) Unbinding.
Then a large number of monks went to the Blessed One and on arrival,
having bowed down to him, sat to one side. As they were sitting there,
they said to him, "Lord, the clansman named Punna, whom the Blessed
One instructed with a brief instruction, has died. What is his
destination? What is his future state?"
"Monks, the clansman Punna was wise. He practiced the Dhamma in
accordance with the Dhamma and did not pester me with issues related
to the Dhamma. The clansman Punna is totally unbound."
SN 35.88
The Buddha when faced with the bandit and murderer Angulimala, employed psychic powers apparently, in addition to his wisdom in the method of teaching.
Carrying his robes & bowl, he went along the road to where Angulimala
was staying. Cowherds, shepherds, & farmers saw him going along the
road to where Angulimala was staying, and on seeing him said to him,
"Don't go along that road, contemplative, for on that road is
Angulimala: brutal, bloody-handed, devoted to killing & slaying,
showing no mercy to living beings. He has turned villages into
non-villages, towns into non-towns, settled countryside into unsettled
countryside. Having repeatedly killed human beings, he wears a garland
made of fingers. Groups of ten, twenty, thirty, & forty men have gone
along that road, and even they have fallen into Angulimala's hands."
When this was said, the Blessed One kept going in silence. ....
Then Angulimala saw the Blessed One coming from afar and on seeing
him, this thought occurred to him: "Isn't it amazing! Isn't it
astounding! Groups of ten, twenty, thirty, & forty men have gone along
this road, and even they have fallen into my hands, and yet now this
contemplative comes attacking, as it were, alone and without a
companion. Why don't I kill him?" So Angulimala, taking up his sword &
shield, buckling on his bow & quiver, followed right behind the
Blessed One.
Then the Blessed One willed a feat of psychic power such that
Angulimala, though running with all his might, could not catch up with
the Blessed One walking at normal pace. Then the thought occurred to
Angulimala: "Isn't it amazing! Isn't it astounding! In the past I've
chased & seized even a swift-running elephant, a swift-running horse,
a swift-running chariot, a swift-running deer. But now, even though
I'm running with all my might, I can't catch up with this
contemplative walking at normal pace." So he stopped and called out to
the Blessed One, "Stop, contemplative! Stop!"
"I have stopped, Angulimala. You stop."
Then the thought occurred to Angulimala, "These Sakyan contemplatives
are speakers of the truth, asserters of the truths, and yet this
contemplative, even while walking, says, 'I have stopped, Angulimala.
You stop.' Why don't I question him?"
MN 86
While violence and destruction is strongly discouraged in Buddhism, it is ok for a bonafide ruler or government ("wheel-turning monarch") to establish police and armed forces to:
- protect and guard the people
- ensure peace
- ensure that justice prevails
This generally applies to lay persons and not monks.
‘But sire, what are the noble duties of a wheel-turning monarch?’
‘Well then, my dear, relying only on principle—honoring, respecting,
and venerating principle, having principle as your flag, banner, and
authority — provide just protection and security for your court,
troops, aristocrats, vassals, brahmins and householders, people of
town and country, ascetics and brahmins, beasts and birds. Do not let
injustice prevail in the realm. Pay money to the penniless in the
realm.
