Re: Suwariwaza and Internal Training
My take on suwariwaza changed after I couldn't do it anymore (knee injury).
Initially when others would do kokyudosa I would do it standing. But I felt this was missing the point of the exercise. So I tried doing it sitting cross-legged. And it was very interesting...it is what taught me, very quickly, the difference between "hips" and "center."
Sitting in seiza, you can rise up, swivel, pivot, etc.
Sitting cross-legged you are pretty rooted....so you have no recourse but to experiment with relaxation, extension, intent, and "moving your insides." It's an endlessly fascinating exercise.
