Breaking is far removed from the demonstration of brute strength and ego that is often displayed in the movies.
Breaking is a demonstration of skill meeting technique meeting mind-set. It is the coming together of your teachings and your understanding of the concepts behind the techniques.
To break an object an individual needs to show absolute focus, belief and accuracy in their application, balancing control over their physical and mental attributes.
It will only be successful when the foundation techniques are developed and understood.
Whilst it is impressive to witness the break is a very personal practice, acting like a litmus test of an individual's state of mind and focus as well as correct application.
Breaking is only developed later in training when an individual is ready both physically and mentally.
