“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.”

“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.”

“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.”

“At the center of your beingyou have the answer;you know who you areand you know what you want.”

“Not-knowing is true knowledge.Presuming to know is a disease.First realize that you are sick;then you can move toward health.”

“Without opening your door,you can open your heart to the world.Without looking out your window,you can see the essence of the Tao.The more you know,the less you understand.The Master arrives without leaving,sees the light without looking,achieves without doing a thing.”

“I know hereby what advantage belongs to doing nothing (with a purpose).”
