“Thirty spokes share one hub in non-being lies the use of the cart knead clay to make vessels in non-being lies the use of the vessel cut out doors and windows to make a housetherefore form being comes what is usable and from non-being comes what is essential.”

“The thirty spokes unite in the one nave; but it is on the empty space (for the axle), that the use of the wheel depends.”

“Clay is fashioned into vessels; but it is on their empty hollowness, that their use depends.”

“When pure sincerity forms within, it is outwardly realized in other people's hearts.”

“Allow the heart to empty itself of all turmoil! Retrieve the utter tranquility of the mind from which you issued.Although all forms are dynamic,and we all grow and transform,each of us is compelled to return to our root. Our root is quietude.”

“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.”
