Aside from the first being more a principle of the body and the second a principle of the mind, what is the interplay...between relaxing completely and extending ki?
Howdy,
It has been my experience that you can't have one without the other, and that too much of one also cancels out the other.
In a parallel example to Ki-Aikido, in order to do calligraphy well, one needs to develop a high level of "relaxed concentration." Your hand can't be limp, nor should it be tense. You have to be able to hold the brush firmly and move it where you want to, and yet do it without tension or worry. My teacher had a very calm yet active style with the brush that I'm still working to emulate. The goal is to find the maximum level of "flow" (check out Mihaly Csikszentmihalyi) where correct form and thoughtless movement find a balance. This happens effortlessly when body and mind are one--and with a fair amount of good training.
We've all seen Ki tests where folks are too relaxed and they get pushed over or moved because they were thinking too small, too "local." There is no connection to their environment (dojo, tester, audience) due to laziness--for want of a better word. Then there are those who narrow their concentration in an effort to _Extend Ki_ (known in these parts as "extending face") and send so much of their thought/focus forward or whatever direction the test is in that they are far from relaxed and easily disturbed.
Yes, somewhere in the middle is best.
Now if I just had a map that showed me how to get there....
