Firstly, I'd like to mention that the circular and linear concepts stem from my formal Taijiquan education. Just to be clear, t'was not my brilliant idea.
Wushuer, you quoted:
<Seek the straight in the curved and the curved in the straight> and used An as an example.
Just to clarify your conveyance with some concrete addition and to make sure I understand exactly what you mean.
In An, I see a curved, circular motion (at the apex of transition most clearly...as David alluded to with the 'swimming' post).
There is a subtle circularity to the whole 'pull back-push forward' process, while there is also a more visible overall linear effect.
This duality seems to permeate the form.
I believe the use of circular motion to be directly linked with that very special Taijiquan momentum concept.
Momentum, difficult word to use in Taijiquan circles, because of it's unique implications.
Taijiquan seems to "eliminate" some forms of momentum...while at the same time "promoting" other types of momentum...(ooph, this is difficult to understand and explain).
Taijiquan seems to use momentum in a very specific manner to gain the effects of mass x momentum = power, by making the momentum a more efficient process.
Momentum, with the condition of "Yong Yi, Bu Yong Li" (Use intent, not strength) .
Would anyone care to clarify my thoughts on momentum?
P.S. ....Wushuer, just thought I'd let you know.... your use of the word "relaxative" might draw some smiles and chuckles...it has some rather humorous implications...
