To use what has a boundary to pursue what is limitless is dangerous; with this knowledge, if we still go after knowledge, we will run into trouble. Do not do what is good in order to gain praise.

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.

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.

To go outside what your charge was, and to try to solve everything yourself, is dangerous.
