Taoism (also spelled Daoism; see below) refers to a philosophical and religious tradition that has influenced the people of East Asia for more than 2,500 years.
The word 道, Tao (or Dao, depending on the romanization scheme), is often translated as "path" or "way", but with a myriad of nuances in mythology and Chinese philosophy.
Taoist propriety and ethics emphasize the Three Jewels of the Tao: compassion, moderation, and humility, while Taoist thought generally focuses on nature, the relationship between humanity and the cosmos (天人相应); health and longevity; and wu wei (action through inaction). Harmony with the Universe, or the source thereof (Tao), is the intended result of many Taoist rules and practices.
Reverence for ancestor spirits and immortals is common in popular Taoism. Organized Taoism distinguishes its ritual activity from that of the folk religion, which some professional Taoists (Dàoshi) view as debased. Chinese alchemy (including Neidan), astrology, cuisine, Zen Buddhism, several Chinese martial arts, traditional Chinese medicine, feng shui, and many styles of qigong have been intertwined with Taoism throughout history.
