The knowledge of the ancients reached the highest point-the time before anything existed. This is the highest point. It is exhaustive. There is no adding to it.
ZhuangziThere is danger for the eye in seeing too clearly, danger for the ear in hearing too sharply and danger to the heart from caring too greatly.
ZhuangziWhen I look at what the world does and where people nowadays believe they can find happiness, I am not sure that that is true happiness. The happiness of these ordinary people seems to consist in slavishly imitating the majority, as if this were their only choice. And yet they all believe they are happy. I cannot decide whether that is happiness or not. Is there such a thing as happiness?
ZhuangziIf 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.
