Re: Aikido and being Christian
I don't know what to tell you other than that "emptying the mind" is an expression that I have both heard and read in regards to certain kinds of meditation, including the Zen form. Maybe its just a turn of phrase intended to express what you have said, but, then again, maybe not. In any case, I know of martial artists who do attempt to make their minds perfectly empty of thought. They do this in order to be a "mirror" or "still pond" mentally so that they can simply respond without conscious thought to any attack. Some do it in an attempt to tap into power beyond themselves. An empty mind, they believe, is necessary to combine the limitless spiritual with the limited physical within themselves. You'll find this sort of thinking in many New Age books on meditation.
Take it easy!
