I had the luck to spend a little time in Hombu dojo last february, and got some interesting perspectives on the theme for 2010. During an Ayase Class, Soke referred to (or asked us to have) bad taijutsu! He spoke on doing things only half (Chuto Hanpa), with no intention, but to remember that beneath no intention flows a sea of intention. Later that week he said (after effortlessly throwing the opponents around) the reason he could still do this in his 80ties is that he uses no power.
So by piecing things together from talks with Bujinkan residents, Shihan classes and Sokes teachings i got to this perception of what Soke shows us.
Dont punch/kick/lock/fight or have any intention to do so. If your kick naturally evolves because the Ukes position in Kukan/time/space invites the kick to do so, just let the kick happen without intention. More importantly, dont think, even if the kick misses, just react naturally again. Be patient in the now, and let Uke deside his own faith.
Beneath this mindset, or no mindset (Mushin), there can/will be a subconsious whiff of intention to manipulate Uke to walk his eye into your finger or over the cliffside. But this intention must not be to intent, or the very mindset is gone, and you are back to fighting attitude.
Maybe the principle of having both a Tai no kamae (body posture) and a (different) Kage no kamae (shadow posture) is another way to express this. Sven Eric taught this many years ago, but that concept allways seemed a bit weird and unpractical to me, until recently.
If you think you know this, you don´t, and if you don´t know it, you are on the right track.
This is naturally very hard to do on a practical level, your mind takes you off in many directions during training. If you get called up in Hombu, to show your version of Sokes teaching, your ego wants you to look good. So if that takes over, you usually end up not looking good. The ‘simple’ cure is to let go of the ego, and be “ligeglad”. This danish word normally means don´t care, but consists of two parts meaning equally + happy. So by being “equally happy” you just naturally do (care), but without thought. This happened to me in Hombu, and i think because of this mindset (and some previous 20+ years of Kihon and a good uke) i succeded “looking good”/controlling my uke.
Then the next part is to keep this mindset and control of Kukan with a big, strong mean Uke who really pushes you, and not just your normal friendly Uke that you know well. The step beyond that to keep the mindset in Jissen (real fight) or Jissen (life).
So luckily, I still have more training opportunities. I hope you do too, and that this will aid you along the way.
