Most scholars generally define the key points of North dandou (a sect of Taoism) and South dandou with ”mind first, body second” and ”body first, mind second”. This saying is simply too simple. Actually, mind practice of South dandou's ”mind second” is deeply based on body practice. This kind of practice can achieve a higher and broader state of mind than North dandou's ”mind first” which says ”mix up with secularism”, ”abandon your wife and children”, ”accumulate good deeds” and so on. However, outer historic causes and inner doctrinal causes make North dandou tend to suggest ”emphasize mind, de-emhpasize body”, ”mind first, body second”. In view of historic causes, because North dandou developed between Jin Dynasty and Yuan Dynasty, a chaotic time, it then focuses on mind practice instead of body practice (heart, fire, kidney, water). In view of doctrinal causes, due to an aim of ”yan shen” which means ”body consists with mind”, it then has to look back at Chi practice after mind practice. Such ”yan shen” is not only unlimited to karma, but also superior to ”in shen” (only mind, no body). The absorbed concept from Buddhist ”four big and fake combination” is purposed to give away all kinds of secular desires for practicers. So they can totally achieve mind practice.
