The long form delved deeper into the principles of Tai Chi. In terms of the sequence it pretty much followed the classical Yang style.
We began to explore cross energy, applications, where to put the mind in the posture and more. Some postures differed from the short form, such as single whip, in order to explore the emphasis that John gave them.
It would take me anywhere between 18 - 30 minutes to complete the long form depending on factors such as speed and sinking. If I had time I would practise 3 forms, one after the other. Even though I now mostly practise traditional Sun style, I always do 3 sword forms and 3 empty hand forms.
By the time you get to the third form you find a deepening practise of spirit.
