The uncarved block and effortless action from the Daodejing and other Daoist texts are a great entry point for anyone into Daoism. They seem to be particularly relevant for anarcho-primitivists and rewilding folks in that effortless action seems to be the underlying principle of a successful hunter-gatherer culture and that are modern civilization is so against effortless action. We seem to be stuck in effortful action all the time.
As for other sources, over the last few years there have been more and more books on tales of the Daoist Immortals. These are stories of irreverent sages and wanderers who disdained agriculture and civilization and lived in the mountains eating wild medicinal herbs and practicing being one with the Dao. The stories are funny, interesting, and definitely point to a different way of being than the one our society tries to cram down our throats. These stories might be another way for people to explore Daoism if they aren’t in for the paradoxical poetry of the Daodejing.
