That knowledge which stops at what it does not know, is the highest knowledge.

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 you do what is bad be sure to avoid the punishment. Follow the Middle Course, for this is the way to keep yourself together, to sustain your life, to care for your parents and to live for many years.

The birth of a man is the birth of his sorrow. The longer he lives, the more stupid he becomes, because his anxiety to avoid unavoidable death becomes more and more acute. What bitterness! He lives for what is always out of reach! His thirst for survival in the future makes him incapable of living in the present.

He who regards all things as one is a companion of Nature.

Take care of your body, then the rest will automatically become stronger.

When there is no more separation between 'this' and 'that,' it is called the still-point of the Tao. At the still point in the center of the circle one can see the infinite in all things.

Listening stops with the ears, the mind stops with recognition, but spirit is empty and waits on all things.
