“Know glory but cleave to humiliation.”

“To know and yet (think) we do not know is the highest (attainment); not to know (and yet think) we do know is a disease.”

“Knowing others is Wisdom, knowing yourself is Enlightenment”

“To know that you do not know is the best.To think you know when you do not is a disease.Recognizing this disease as a disease is to be free of it.”

“The wise man is one who, knows, what he does not know.”

“A man who knows how little he knows is well, a man who knows how much he knows is sick. If, when you see the symptoms, you can tell, Your cure is quick.A sound man knows that sickness makes him sick and before he catches it his cure is quick.”

“He who speaks does not know; he who knows does not speak”
