In The Book Of Poetry

Only One Who Bursts With Enthusiasm Do I Instruct; Only One Who Bubbles With Excitement Do I Enlighten. If I Hold Up One Corner And You Do Not Come Back To Me With The Other Three, I Do Not Continue The Lesson.

When A Man's Knowledge Is Sufficient To Attain, And His Virtue Is Not Sufficient To Enable Him To Hold, Whatever He May Have Gained, He Will Lose Again.

Have No Friends Not Equal To Yourself.

The Superior Man Is Satisfied And Composed; The Mean Man Is Always Full Of Distress.

Be Loyal And Trustworthy. Do Not Befriend Anyone Who Is Lower Than Yourself In This Regard.
