"If the Tao could be served up, everyone would serve it up to their lords. If the Tao could be offered, there is no one who would not offer it to their parents. If the Tao could be spoken of, there is no one in the world who would not speak of it to their brothers and sisters. if the Tao could be passed on, there is no one who would not pass it on to their heirs. However, it obviously cannot be so and the reason is as follows. If there is no true centre within to receive it, it cannot remain;if there is no true direction outside to guide it,it cannot be received."
