Hendricks,
have you been reading my posts again? Or are you bringing up Bai Jong and facing out of some bizarre coincidence.
Ying is the only the first energy. Structural energy.
It is not dead or lifeless. It is not merely a shape.
To think otherwise is low level understanding.
Ying is knowing yourself. As in without knowing yourself, one can not begin to know their opponent. Yes, it's an old saying we've all heard so many times. But one has to directly Face this truth just like all other truths and can not run away from it.
Just like in combat, if you flow all the time without any real guard or breaks to control the energy, then eventually someone is going to pop you like one big water balloon.
All your precious flow will have leaked out everywhere uselessly and you'll find your center has been nailed to the wall.
Just sayin...
Lau is important, but it is not the end all.
