Great topic! Going to use it as a chance to better formulate them to myself
When I started learning TJQ I just wanted to do it for fun, without any other practical goal.
Later on when that stretchy feeling inside had grown into the feeling of “force-paths” within the body, I started focusing more on developing the elasticity out of bi-directional forces that would allow to generate and transmit power. After that twisting them into the spirals and so on. Making the connective tissue more pliable is the best way to increase the quality of life, and the internal movement is a nice exercise targeting it.
Being able to apply that power led to the desire to see how TJQ can be used as a martial method. What the original meaning of the form movements was and how push hand patterns can be expanded into a wider repertoire of the connected movement. It’s just interesting to go through the discovery process
The highest goal is probably just becoming good at it. The old Chinese adage of exploring the greater Dao through attaining excellence at a smaller one does resonate with me a lot. Being good at something specific helps with being better at living your life in general.
