Most martial arts meet conflict with resistance.
Tai chi is different; it requires the student to blend, to join, to avoid blocking the path of force.
This process is called 'yielding', and the joining may be seen as 'mutual arising'.
It is the completion of the yin/yang diagram.
Given the prevalence of conflict in our culture and the common urge to fight, the challenge of non-contention is daunting.
By overcoming fear and using the physics skilfully, a tai chi person can meet the incoming attack softly, redirect the force and avoid unnecessary violence.
A person may choose to apply this methodology throughout all aspects of their life.
