The articles listed here are a selection of informative writings that offer insights into the core skills of tai-chi. They represent the thinking from a cross section of tai-chi styles and can be broadly divided between works from Chinese masters which have been translated into English by knowledgable people and English speaking exponents of the art which are written in plain English. Some are illustrated with links to selective examples on utube. Also included are some descriptions of tai-chi forms with utube examples. Practitioners of the neijia of all levels will find something of interest here.
The following three interlinked articles by Mike Sigman are on the baseline internal skills of tai-chi and are best read sequentially.
