The mind remains undetermined in the great Void. Here the highest knowledge is unbounded. That which gives things their thusness cannot be delimited by things. So when we speak of 'limits', we remain confined to limited things. The limit of the unlimited is called 'fullness.' The limitlessness of the limited is called 'emptiness.' Tao is the source of both. But it is itself neither fullness nor emptiness

The hidden so-called scholars of old did not hide themselves and refuse to be seen. They did not close the door on their words and refuse to let them out. They did not shut away their wisdom and refuse to share it. But those times were all haywire. If it had been possible for them to act, they could have done great things, bringing all to Oneness without any sign of doing so. However, the times were not favorable and it was not possible, so they put down deep roots, remained still and waited. this was the Tao by which they survived.

If there is existence, there must be non-existence. And if there was a time when nothing existed, there must have been a time before that - when even nothing did not exist. Suddenly, when nothing came into existence, could one really say whether it belonged to the category of existence or non-existence?

As regards the quietude of the sage, he is not quiet because quietness is said to be good. He is quiet because the multitude of things cannot disturb his quietude. When water is still, one's beard and eyelashes are reflected in it. A skilled carpenter uses it in a level to obtain a measurement. If still water is so clear, how much more are the mental faculties! The mind of the sage is the mirror of heaven and earth in which all things are reflected.

Life is finite, While knowledge is infinite.

If you persist in trying to attain what is never attained (It is Tao's gift), if you persist in making effort to obtain what effort cannot get, if you persist in reasoning about what cannot be understood, you will be destroyed by the very thing you seek. To know when to stop, to know when you can get no further by your own action, this is the right beginning!

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