My mindset has changed so much since I got to Japan. Especially for strikes. I took away the real essence of systema. It is not to hurt others but to relax them and take away the aggression. That was a huge shift for me. Also, when someone does something to me it creates tension within my body. So when I deal with that tension naturally the body will show you where to move. Also about keeping the body and keeping the tension at the area of contact but relax the rest of the body and keep form.
