How is it possible to acquire something that supposedly comes without effort?
Tao is obvious, right in our face (Nature does not have to insist...) but this obviousness is precisely the reason we miss it. One must learn to read its subtle language. To observe the cyclic phenomena we must empty our minds of old baggage.
Let's observe poertically! Wu-wei is a form of universal poetry that is acted through virtue (... to produce but not possess, to care but not to control, to lead but not to subjugate.
When our observation becomes efortless, wu-wei happens. Remember, wu-wei is not passive, but active. We choose the world.
Tao is "what is": the rule of the universe.
The universe is deathless,
Is deathless because, having no finite self,
It stays infinite.
A sound man by not advancing himself
Stays the further ahead of himself,
By not confining himself to himself
Sustains himself outside himself:
By never being an end in himself
He endlessly becomes himself.
To yield is to [be preserved whole.
To be bent is to become straight.
To be empty is to be full.
To be worn out is to be renewed.
To have little is to possess.
To have plenty is to be perplexed.
Therefore the sage embraces the ONE.
