True happiness comes to those who live at peace with their fellows. The aim of all should be to learn peace and live peacefully with all men.
Guard against evil deeds: control the body. Eschew evil deeds and do good. Guard against evil words: control tongue. Eschew evil words and speak good ones. Guard against evil thoughts: control the mind. Eschew evil thoughts and think good ones.
A word spoken in wrath is the sharpest sword; covetousness is the deadliest poison; passion the fierest fire; ignorance is the darkest night.
Let no one deceive another, let no one despise another, let no one out of anger or resentment wish to harm another.
