Wu Wei= Effortless action

 The Way is ever without action, yet nothing is ever left undone. By Lao Tzu

Here’s more context

In the pursuit of learning one knows more every day;
In the pursuit of the way one does less every day.
One does less and less until one does nothing at all,
And when one does nothing at all there is nothing that is undone.

I ask Clausde: 

That line points to wu wei — usually translated "non-action," though "effortless action" gets closer to the meaning. It's not about passivity or doing nothing. It's about acting in a way that doesn't force things against their nature.

Think of water. It doesn't strain or struggle, yet it carves canyons and always finds its way downhill. Or think of a skilled craftsman who works with the grain of the wood instead of against it — less effort, better result. Lao Tzu's point is that when you stop forcing outcomes, stop over-managing, stop pushing your will onto every situation, things tend to resolve themselves more naturally and completely than when you grasp at them.

The paradox ("nothing is left undone") is the payoff: forced action often creates resistance and unintended problems, while aligned, minimal action tends to accomplish more with less friction. It shows up in leadership too — a ruler (or manager, or parent) who governs by trusting people and removing obstacles, rather than micromanaging, often gets better results than one who controls everything.
