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

“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.”

“Knowing others is intelligence;knowing yourself is true wisdom.Mastering others is strength; mastering yourself is true power.”

“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.”

“Look, and it can't be seen.Listen, and it can't be heard.Reach, and it can't be grasped.Above, it isn't bright.Below, it isn't dark.Seamless, unnamable,it returns to the realm of nothing.Form that includes all forms,image without an image,subtle, beyond all conception.Approach it and there is no beginning;follow it and there is no end.You can't know it, but you can be it,at ease in your own life.Just realize where you come from:this is the essence of wisdom.”

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

“If you understand others you are smart.If you understand yourself you are illuminated.If you overcome others you are powerful.If you overcome yourself you have strength.If you know how to be satisfied you are rich.If you can act with vigor, you have a will.If you don't lose your objectives you can be long-lasting.If you die without loss, you are eternal.”
