Hold faithfulness and sincerity as first principles.
A superior man is modest in his speech, but exceeds in his actions.
The parents age must be remembered, both for joy and anxiety.
The commander of the forces of a large State may be carried off, but the will of even a common man cannot be taken from him.
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.
