Resistence in the truest form is he works his sh*t, you work yours, and who ever comes out on top, well, they come out on top.
That really doesn't cover it though. The best thing is someone who is better than you challenging your sh*t with his and them being capable of showing you how to handle their sh*t. Then finding teachers with better sh*t!! Otherwise your sh*t remains stagnant and attached to your teachers limits!
Everyone looks as their teacher as woo woo! In examining investment in the Martial arts it better to wait ten years to find a good teacher then spend five with the wrong one.
Some methods to train aiki are just simply superior to others.
Hope to see you soon. I will be in P.A. in Dec and Atlanta in Jan.
