Tsze-Kung asked, โIs there one word with which to act in accordance throughout a lifetime?โ The Master said, โIs not reciprocity such a word? What you do not want done to yourself, do not do to others.
ConfuciusThe superior man, when resting in safety, does not forget that danger may come. When in a state of security he does not forget the possibility of ruin. When all is orderly, he does not forget that disorder may come. Thus his person is not endangered, and his States and all their clans are preserved.
