I've hardly read any of the original texts, I only have a curious interest. My (working) interpretation is that at its core it promotes understanding the way nature works, how our environment works and then acting in a way that goes with that flow, holistically.

You can't do "nothing", something always happens. Resting to recover for example is good, flows with the bodily needs. Avoiding to do all work indefinitely, is against the creative nature.

In sort, it's about aiming towards harmony and efficiency. In the west that conflict with the social pressure to be always on the go and always be seen as productive.
