Ledyard Sensei, I generally agree with what you've said, but one paragraph confused me:
George S. Ledyard
It's not that the ideas are not true or that they are not manifesting their values in their lives... Mother Teresa was an extremely, profoundly, spiritual person. She lived her spirituality every day. But she didn't do Aikido. It is only Aikido when you can manifest this knowledge in ones waza. The understanding of Aikido is a Mind / Body understanding that reveals and demonstrates spiritual insight. Spiritual insight without the mind / body manifestation isn't Aikido. It's not wrong or in any way inferior, it just isn't Aikido. That's what makes Aikido such a unique practice.
I don't get it. Are you saying that Aikido is the only practice in which a physical practice is a manifestation of a spiritual state?
