Our kung fu follows the principle of "allowing" rather than "doing". This means that we don't force anything to happen via tension or contraction, but rather allow things to happen, via fullness and inflation. Rather than inhaling, we allow the breath to fill the lungs. Rather than lifting the arms, we allow them to rise. Rather than shifting the weight, we allow it to drain from one foot into the other. Rather than lifting the leg, we allow it to float upwards. And so on and so forth.
This is the first secret of our kung fu.
