The theory of Taijiquan is important for me, because with its help I can make predictions. I can check if the prediction is right or wrong with my teacher Ma Jiangbao, my Tai Chi friends or through practice. Therefore a theory is much more than a description of a movement or techniques. It is a tool to guide me.
Now I read the following about the word 'theory':
"The word 'theory' comes from the greek verb theorein, what mean 'to look at' or 'to see possibilities."
Isn't this wonderful.
All the best
