The man of true greatness never loses his child's heart.

Every duty is a charge, but the charge of oneself is the root of all others.

The myriad things are complete in us. There is no greater joy than to reflect on ourselves and become sincere.

Virtue alone is not sufficient for the exercise of government; laws alone cannot carry themselves into practice.

Only those who develop their minds and spirits to the utmost can serve Heaven and fulfill their own destinies.

He who exerts his mind to the utmost knows his nature.

Those who follow the part of themselves which is great are great men; those who follow the part which is little are little men.
