A happy union with wife and child is like the music of lutes and harps.
Do not answer the person whose questions are vile. Do not question a person whose answers are vile.
Act with kindness but do not expect gratitude.
If one is guided by profit in one's actions, one will incur much ill will.
Learn as though you would never be able to master it; hold it as though you would be in fear of losing it.
In your promises cleave to what is right, And you will be able to fulfill your word.
