"The more you know, the less you understand."

"Empty your mind of all thoughts. Let your heart be at peace. Watch the turmoil of the world, but let your serenity remain. Return to the root. This is tranquility. This is returning to your destiny."

"Without going out of the door, one can know the whole world. Without peeping through the window, one can see the Way of Heaven. The further one goes, the less one knows."

"To know yet to think that one does not know is the highest [attainment]. Not to know yet to think that one knows is a disease."

"The sage's Way is to act and not to contend."
