In a river mist, if another boat knocks against yours, you might yell at the other fellow to stay clear. But if you notice then, that it's an empty boat, adrift with nobody aboard, you stop yelling. When you discover that all the others are drifting boats, there's no one to yell at. And when you find out you are an empty boat, there's no one to yell.
ZhuangziTo 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.
