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.
ZhuangziThere is a saying that Heaven is internal, humanity external and Virtue comes from the Heavenly. Know Heaven and humanity's actions, root yourself in Heaven and follow Virture.Then you can bend, stretch, rush forward or hold back, because you will always return to the core and it will be said you have achieved the supreme.
ZhuangziYour mind must become one, do not try to understand with your ears but with your heart. Indeed, not with your heart but with your soul.
ZhuangziCompare birth with death, compare death with life; compare what is possible with what is not possible and compare what is not possible with what is possible; because there is, there is not, and because there is not, there is.
Zhuangzi
