Shape clay into a vessel;
It is the space within that makes it useful.
Cut doors and windows for a room;
It is the holes which make it useful.
Therefore benefit comes from what is there;
Usefulness from what is not there.
Greed for enlightenment and immortality is no different than greed for material wealth. It is self-centered and dualistic, and thus an obstacle to true attainment. Therefore these states are never achieved by those who covet them; rather, they are the reward of the virtuous.
If the Great Way perishes there will morality and duty. When cleverness and knowledge arise great lies will flourish. When relatives fall out with one another there will be filial duty and love. When states are in confusion there will be faithful servants.
Other people are joyous, like on the feast of the ox, like on the way up to the terrace in the spring. I alone am inert, giving no sign, like a newborn baby who has not learned to smile.
