High and low, long and short—all these opposites support each other and can't exist without one another.
The sages, the super-wise Tao dudes, use this knowledge of dualities to live their lives with the Tao.
For one, they live with the wu wei, or unattached action.
Context Alert! Wu wei (also known as unattached action, effortless action, or the action of no action) is a big-deal concept in Taoism. It's slippery to define, but mostly it's about living in the moment, being relaxed, and not obsessing over outcomes.
Anyway, the sages also do other cool stuff like teach the power of silence and live life without valuing material things.
This chapter ends by giving us the secret to the sages' success: they don't dwell on success, so it never goes away.
