Taoism is an East Asian religion founded in ancient China with many schools or denominations, of which none occupies a position of orthodoxy and co-existed peacefully.[1] Taoist branches usually build their identity around a set of scriptures, that are manuals of ritual practices.[2] Scriptures are considered "breathwork", that is "configurations of energy" (qi), embodiments of "celestial patterns" (tianwen),[3] or "revelations of structures" (li).[4]
The earliest Taoist schools emerged during the late Eastern Han dynasty (25-220 CE).[5] They blossomed especially in the region of Shu, modern-day Sichuan.[6] From the 12th and 13th centuries onwards several smaller branches merged into larger ones, but in turn, side-schools developed around the large traditions.[7] In modern times the existing schools tend to be classified under few overarching headings, in most cases under two main denominations: Quanzhen Taoism and Zhengyi Taoism.
