All is flux; nothing stays still.
One must know that war is common, justice is strife, and everything happens according to strife and necessity.
Eyes and ears are poor witnesses to people if they have uncultured souls.
Couples are wholes and not wholes, what agrees disagrees, the concordant is discordant. From all things one and from one all things.
Change is the only constant.
The phases of fire are craving and satiety.
