Rabban Shime'on ben Gamliel said, On three things the world stands; on Judgment, and on Truth, and on Peace.
רַבָּן שִׁמְעוֹן בֶּן גַּמְלִיאֵל אוֹמֵר, עַל שְׁלשָׁה דְבָרִים הָעוֹלָם עוֹמֵד, עַל הַדִּין וְעַל הָאֱמֶת וְעַל הַשָּׁלוֹם…
Pirkei Avot 1:18
The same idea in other traditions
Truth is higher than everything; but higher still is truthful living.
Blessed are the peacemakers: for they shall be called the children of God.
O ye who believe! Fear Allah, and (always) say a word directed to the Right:
Let us live happily then, not hating those who hate us! among men who hate us let us dwell free from hatred!
'Men frequently apply punishment wrongly: the innocent are put in prison, and the perpetrator of the crime is set at liberty.'
He through whom the world is not agitated, and who is not agitated by the world, who is free from joy and anger and fear and agitation, he too is dear to me.
Thou hast come to draw men to union with me, / Not to drive them far away from me. / So far as possible, engage not in dissevering; / 'The thing most repugnant to me is divorce.' …
The Master said, "Yu, shall I teach you what knowledge is? When you know a thing, to hold that you know it; and when you do not know a thing, to allow that you do not know it;—this is knowledge."
When the Tao prevails in the world, they send back their swift horses to (draw) the dung-carts. When the Tao is disregarded in the world, the war-horses breed in the border lands. There is no guilt greater than to sanction ambition; no calamity greater than to be discontented with one's lot; no fault greater than the wish to be getting. Therefore the sufficiency of contentment is an enduring and unchanging sufficiency.
