The concept of Sen Sen No Sen to me is really a premptive strike in a reality based situation. To me this proves once again that the the saying there in no first attack in karate is false because we don't wait to be attacked if we sense it or see it. So where does it come from ? And Why ? Who put that concept out there and what did they mean by it ? I think we all know as karateka that we just don't go out and start fights but, at the same time we are not going to wait to be attacked. So the concept that there is no first attack in karate has always confused me. Thoughts ?
