Buddhism Scriptures

The monk looks for peace within himself, and not in any other place.  For
when a person is inwardly quiet, there is nowhere a self can be found;
where, then, could a non-self be found?

There are no waves in the depths of the sea; it is still, unbroken. It is
the same with the monk. He is still, without any quiver of desire,
without a remnant on which to build pride and desire.

Buddhism. Sutta Nipata 919-20

Victory breeds hatred, for the defeated live in pain. Happily live the
peaceful, giving up victory and defeat.

Buddhism. Dhammapada 201

Some children were playing beside a river. They made castles of sand, and
each child defended his castle and said, "This one is mine." They kept
their castles separate and would not allow any mistakes about which was
whose. When the castles were all finished, one child kicked over someone
else's castle and completely destroyed it. The owner of the castle flew
into a rage, pulled the other child's hair, struck him with his fist and
bawled out, "He has spoiled my castle! Come along all of you and help me
to punish him as he deserves." The others all came to his help. They beat
the child with a stick and then stamped on him as he lay on the ground....
Then they went on playing in their sand castles, each saying, "This is
mine; no one else may have it. Keep away! Don't touch my castle!" But
evening came, it was getting dark and they all thought they ought to be
going home. No one now cared what became of his castle. One child
stamped on his, another pushed his over with both hands. Then they turned
away and went back, each to his home.

Buddhism Yogacara Bhumi Sutra 4

He brings together those who are divided, he encourages those who are
friendly; he is a peacemaker, a lover of peace, impassioned for peace, a
speaker of words that make for peace.

Buddhism. Digha Nikaya xiii.75, Tevigga Sutta

During the short eons of swords,
They meditate on love,
Introducing to nonviolence
Hundreds of millions of living beings.

In the midst of great battles
They remain impartial to both sides;
For bodhisattvas of great strength
Delight in reconciliation of conflict.
