Re: No Competition in Aikido(excluding Tomiki)
Just to add on from the above we use the rule that it is impossible for resistance to stop Aikido. That's one of our golden rules.
So it is not even seen as opposite to non resistance. It is seen as something which can only be described as a replacement of Aikido. So when thwarted by any resistance the answer is you have somehow entered that game of resistance. It is for the thwarted one to recognize how and why.
To know when you used resistance and when you didn't is the self discipline and honesty needed and so applies to even when successful for being successful when using any resistance to us is failing.
