A perennial question I never fail to get is whether we have qigong in our Tai Chi. Yes, we do but it is not the breathe-in, breathe-out type that is commonly practiced.
The clip below gives an idea of why we don’t practice this type of qigong :-
We can practice our power generation without having to use qigong or breathe-out to issue power. We typically issue power whilst talking normally, as if its a normal activity.
We can do this because our power generation is trained using intent. After years of doing it we actualize the old boxing maxim of eyes arrive, hand arrives which means when the mind arrives, power arrives.
