Yin and yang, male and female, strong and weak, rigid and tender, heaven and earth, light and darkness, thunder and lightning, cold and warmth, good and evil...the interplay of opposite principles constitutes the universe.

Is any one able for one day to apply his strength to virtue? I have not seen the case in which his strength would be sufficient.

If doing what ought to be done be made the first business and success a secondary consideration--is not this the way to exalt virtue?

Listen widely to remove your doubts and be careful when speaking about the rest and your mistakes will be few.

A man who reviews the old so as to find out the new is qualified to teach others.

Behave when away from home as though you were in the presence of an honored guest. Employ the people as though you were assisting at an important sacrifice. Do not do to others what you would not like yourself. Then there will be no feelings of opposition to you, whether it is the affairs of a state that you are handling or the affairs of a family.

Acquire new knowledge whilst thinking over the old, and you may become a teacher of others.
