While I was trying a kote-gaeshi, he explained (Rob translated) that he was directing my pressure to his center through some lines, although I can't say I actually understand the meaning of "inside lines", "outside lines", etc.
I have been exploring the "ten chi jin" exercise without guidance other than what I've read on the aunkai website. That's this form:
It's the second photograph, the subject stands with both hands raised, palms up, fingers pointing outward.
Try standing the same way, but turn the fingers inward instead of outward, palms still up.
Do you notice any difference? How would you describe that?
