Re: kendo's gruelling challenge
Mochida Moriji Sensei talks about his true training starting at the age of 50. He speaks bluntly about how the the lower body loses its life force in one's sixties and how in one's seventies the entire body loses its essence.
The test is whether the 50, 60, and 70 year old can still win against the 20, 30 and 40 something. This is the result of the "training". It takes a lifetime...there are no shotcuts. But, their are insights.
As such, in the beginning we start by using and conditioning our bodies. Later, we "see things" with our mind. We look "internally". Near the end, we choose/follow "aged teachers" that can still produce "results" as if by "mind only".
Some of us, are lucky in our insights. Most never refine the Qi/Ki. Yet, even with refinement, the Qi/Ki never truly belongs to us. Our bodies are only containers. They begin to leak all the "effort/knowledge/refined life force.
As such, We watch our teachers as they "collapse" and in our insecurities we wonder "will there is enough time?".
