How to develop faat ging correctly? and 'Jut ging"?

Nice one Declan .

 

Intersting stuff.

I would just like to add that some internal systems alongside with training jin, use jing in the "essence" sense, to develop internal power, i.e. chi-jing-shen. So, in some sense both "fa jin" and "fa jing" could makes sense in a martial aspect.

 

i see thank you!!

 

The simple answer to your original question is: "When you realise you're hitting a lot harder with less effort and less rigidity.

The ideal answer is: "When your teacher tells you."
