Everyone knows how useful usefulness is, but no one (4:20) seems to know how useful uselessness is. - Zhuangzi

When Yan He was appointed tutor to the crown prince of Wei, son of Duke Ling, he went to consult with Qu Boyu. “Here is a man who is just naturally no good. If I find no way to contain him, he will endanger my state, but if I do try to contain him, he will endanger my life. His cleverness allows him to understand the crimes people commit, but not why they were driven to commit these crimes.10 What should I do?” Peng Boyu said, “Good question! Be careful and cautious and rectify yourself! Be compromising in appearance and harmonious in mind. But even these measures can present problems. Don’t let the external compromise get inside you, and don’t let your inner harmony show itself externally. If you let the external compromise get inside you, it will topple you, destroy you, collapse you, cripple you. If the harmony in your heart shows itself externally, it will lead to reputation and renown, until you are haunted and plagued by them. If he’s playing the baby, play baby with him. If he’s being lawless and unrestrained, be lawless and unrestrained with him. If his behavior is unbounded and shapeless, be unbounded and shapeless with him. You must master this skill to the point of flawlessness. Don’t you know the story of the praying mantis? It flailed its pincers around to stop an oncoming chariot wheel, not realizing the task was beyond its powers. This is how it is for those with ‘great talents.’ Be careful, be cautious! If you irritate him by flaunting your talents, you will be in more or less the same position. Don’t you know how the tiger trainer handles it?

Therefore, in a time of Perfect Virtue, the gait of men is slow and ambling; their gaze is steady and mild. In such an age, mountains have no paths or trails, lakes no boats or bridges. The ten thousand things live species by species, one group settled close to another. Birds and beasts form their flocks and herds; grass and trees grow to fullest height. So it happens that you can tie a cord to the birds and beasts and lead them about or bend down the limb and peer into the nest of the crow and the magpie. In this age of Perfect Virtue, men live the same as birds and beasts, group themselves side by side with the ten thousand things. Who then knows anything about “gentleman” or “petty man”? Dull and unwitting, men have no wisdom; thus their Virtue does not depart from them. Dull and unwitting, they have no desire; this is called uncarved simplicity. In uncarved simplicity, the people attain their true nature.

The man who has forgotten self may be said to have entered Heaven.
