pardon me that I come into the conversation midway, but some of the issues have been addressed before and not put together quite the way they have. Anyway, Wushuer's post sets out his position pretty well.
"Question the first:
>I was trained that your supporting leg is >your yang leg."
Imho, it makes very little difference whether one describes a particular leg as yang or yin at any given time. Imo, yin and yang are not (ideally never?) static. Your description seems reasonable, but is there a difference between a "yang" leg that is resting and a "yang" leg that is kicking? When one kicks, can both leg be yang, or are kicks "yin"? Btw, the same can be applied to simple walking: even the stable leg must move.
>Question the second:
>"Rooting" is a word with too many >definitions.
>In this case, it means "sending energy to >the ground that you will not use for >anything else".
Again, all these are just mhos, and won't get anyone a taxi ride. I don't think that "rooting" is an energy that is sent down. I believe it is something that is allowed to happen, and would happen naturally if we didn't hve the tendency to tense "up." The "downward" energy is produced by gravity, not by any mechanical force generated from the body. It's like imagining a rock moving to try to stabilize itself.

Gee, I guess we may have come to similar conclusions

It makes sense to me.
Can't address number five.
>"Question the sixth:

Do you mean "between your weighted legS"? Personally, I like the approach of really being "single weighted" (literally) as much as possible. But, as you say, sometimes it is necessary to move the center --so the single weight has to move with it.
>Question the seventh:
>Back to the "coiled springs" theory.
>You do NOT "commit" to your yin leg until >you have FELT and are sure of the root.
Well, once you've "committed" to your "yin" leg, it becomes "yang" or no?
>You "coil" the energy in your yang leg, as >you "spring" it to your other leg, there is >a moment of transition where you "feel" our >your root. If you don't have it, you >don't "spring". You reseat or move your yin >leg, test, then "spring" onto it.
This is a little harder for me to get. But, you're running out of time.
>So the idea is the same, you "feel" >or "sense" the root before you commit.
OK, makes sense.
>Again, the idea of "lean" comes into play >in ways I cannot, for all the above reasons >and more, easily explain.
Well, I don't know if it's necessary to turn "lean" into a quality and "not leaning" into a fault.
