Q: How is Tai Chi related to Daoism (Taoism)?

A: Daoism is a very complex study.  The oldest text have been interpreted in many different ways, and along the way many schools of thought have emerged from the roots of the most ancient texts written by Lao Zi and Zhuang Zi. I recommend my own translation of Lao Zi, but to get a simple overview of the basic concepts of Doism and their relation to Tai Chi I also recommend this very informative documentary (23 min).
