"Conquer anger by love. Conquer evil by good. Conquer the stingy by giving. Conquer the liar by truth."
"Hurt not others in ways that you yourself would find hurtful. One should seek for others the happiness one desires for one's self"
Tripitaka Udana-Varga 5:18 (~500 BC)
"The bodhisattva should adopt the same attitude towards all beings, his mind should be even towards all beings, he should not handle others with an uneven mind, but with a mind which is friendly, well-disposed, helpful, free from aversions avoiding harm and hurts, he should handle others as if they were his mother, father, son, or daughter. As a savior of all beings should a bodhisattva behave towards all beings. So should he train him- self if he wants to know full enlightenment."
