Taoism or Daoism refers to a variety of related philosophical and religious traditions and concepts that have influenced East Asia for over two millennia and the West for over two centuries. The word 道, Tao (or Dao, depending on the romanization scheme), means 'path' or 'way', although in Chinese folk religion and philosophy it has taken on more abstract meanings. Taoist propriety and ethics emphasize the Three Jewels of the Tao: compassion, moderation, and humility. Taoist thought generally focuses on nature, men-cosmos correspondence (天人相應), health, longevity, wu wei (action through inaction), liberty, and spontaneity.
Reverence for ancestor spirits and immortals are also common in popular Taoism. Organized Taoism distinguishes its ritual activity from that of the folk religion, which some professional Taoists (Daoshi) view as debased. Chinese alchemy (including Neidan), astrology, cuisine, several Chinese martial arts, Chinese traditional medicine, feng shui, immortality, and many styles of qigong breath training disciplines have been intertwined with Taoism throughout history.
Categorization
There is debate over how, and whether, Taoism should be subdivided. Livia Kohn divided it into the following three categories:
1."Philosophical Taoism" (Daojia 道家) - A philosophical school based on the texts Dao De Jing (道德經) and Zhuangzi (莊子);
2 "Religious Taoism" (Daojiao 道敎) - A family of organized Chinese religious movements originating from the Celestial Masters movement during the late Han Dynasty and later including the "Orthodox" (Zhengyi 正一) and "Complete Reality" (Quanzhen 全眞) sects, which claim lineages going back to Lao Zi (老子) or Zhang Daoling in the late Han Dynasty;
3."Folk Taoism" - The Chinese folk religion.
