Zengzi quotes:

Filial Piety is the principle of Heaven, The righteousness of Earth, And the (proper) conduct of the people.

Daily, I examine myself in three areas. Have I done my best when doing things for others? Have I been trustworthy in my dealings with my friends? Have I revised the lessons I have been taught?

A gentleman makes friends by learning together with others, and he looks to friends to help him cultivate benevolence.

A virtuous man concentrates on his own work, not that of others.
