What you dislike in your superiors, avoid doing to your inferiors. What you dislike in your inferiors, avoid doing when working for your superiors. What you hate in those who are in front of you, do not do to those behind you.
Kong Qiu, or Master Kong as he was known, did not live to see his days of glory. During his lifetime, his views were received with scorn. But that was about two thousand five hundred years ago. A handful of his dedicated followers passed on Confucius' teachings to future generations.
After Confucius' death, his followers published his teachings in the book, The Analects of Confucius.
The superior man... does not set his mind either for or against anything, he will pursue whatever is right. The superior man thinks of virtue, the common man of comfort.
A man should demand much from himself, but little from others. When you meet a man of worth, think how you may attain to his excellence. When you meet an unworthy one, then look within and examine yourself.
