"All this "sensing ki in your opponent" is a load of b.s."
Actually, it may not be that big of a load. If you can, try this:
Form a circle and place a blindfolded person in the center (nage). Give everyone else (uke) a bokken or jo (hand works too, but I find it easier to send my ki out with a weapon.) Have one uke point his bokken, sending out lots of ki of course, at the nage and all the others focus somewhere else. The point is to see if nage can sense where the "attack" is coming from.
We've tried it, and the results spooked us a bit. Please let me know on your results should any of you try this. TIA.
