Leaving virtue without proper cultivation; not thoroughly discussing what is learned; not being able to move towards righteousness of which a knowledge is gained; and not being able to change what is not good: - these are the things which occasion me solicitude.

Learning without thought is labor lost; thought without learning is perilous.

Study without reflection is a waste of time; reflection without study is dangerous.

The doer alone learneth.

When learning is purposeful, creativity blossoms. When creativity blossoms, thinking emanates. When thinking emanates, knowledge is fully lit. When knowledge is lit, economy flourishes.

The way which the superior man pursues, reaches wide and far, and yet is secret. Common men and women, however ignorant, may intermeddle with the knowledge of it; yet in its utmost reaches, there is that which even the sage does not know.
