快而不亂,慢而不斷
Fast but not messy, slow but with no break
快則適時,慢在得位*
Quick then timely, slow for gaining position
凡一身之進退動靜,一心為主**
Forwards and backwards, movement or stillness of one's body are all decided by the heart
Speed is a more complex notion in training, and more especially when the organs, the vapours and the mind are combined with body motion. Hence, the opposition between what you do while fighting (the faster the better) and training does not apply for speed. Indeed, while training, normal, fast and slow speed are all applied, each having their own purpose, the skills obtained through each type of speed being all useful while fighting.
