I know Loazi more or less founded the religion/philosophy and I know the basics tenants of wuwei, but it's so full of contradictions I have a hard time understand what they really believe.
For example one of their sayings is "A Dao does nothing yet achieves everything."
Keep in mind that this is subreddit dedicated to history. People here may be able to provide some historical context regarding the devleopment of Daoist doctrine and practice, but if your questions are theological, you may consider a religion-focused subreddit.
