Intention, posture and concept of silk reeling

There are several good points discussed in our chentaichi yahoo group which are derived from topic 'about daily practice (opponent)'. The discussion can be extracted as:
1/ the intention of opponent is necessary.
2/ emphasize the importance of internal aspect of learning.
3/ emphasize the importance of external structure.
4/ mention and question about intention and chi flow.
5/ cultivate internal through relaxed practice.

These statements are all correct if were discussed in the scope as follow:
1/ the intention guides chi. yet
2/ the correct intention can be acquired by hands on teaching. However, the concept of from whom who knows is by degree of knowing. We all recognize that everyone is just approaching in perfecting our Taichi.
3/ not giving correct structure, there are no load path exist,
4/ nor the ability to neutralize under pressure.
4/ as the fluctuation type of dynamic under correct structure is the way to cultivate chi in Taichi,
5/ intention of opponent simulation is suggested in practice through a series of point to verify the proper use of intention.
6/ as the proper intention, the intention points are transferred and linked to earth through aligned bone structure, with fluent and frictionless position adjustment through instance to the other.
7/ the path of those points can be traced into the space spirals,
8/ the space spiral traces are named .the silk reeling (trace). and illustrated in Chen Xing's 'Book of Taichi'.

I like to conclude the discussion as:
1/ insert the opponent simulation in practice as we start,
2/ since we've got the trace, just enjoy the space traces of points in our practice.
