I am glad we are starting to get this in the open, simply because, in laymans's terms whether we take a doctors prescription or and aspirin it is a medication. So too with Aikido's deliverance of pain with technique or individual pressure point, we advance to that level of practice using the pressure points available in any given situation or technique by practice and knowledge. My point being, denying pain being delivered by nerves, whether called pressure points or pain submission, is a moot point. (Moot being a philosophical arguement. That, in working man's terms, means nothing because them educated scholars are beating a dead horse while the world goes on around them, at least in working man's terms.)
Before I practiced Aikido, I had a variety of pain submissions from various jujitsu lessons, but sometimes to get there there were many offensive and defensive dirty tricks to get past punching and kicking? Eventually, judo and jujitsu were that more effective than striking and kicking. When I began to get the hang of Aikido, I saw even more openings, beyond the actual physical manipulations, which became easier to get to with Aikido's flowing harmony.
Now with Aikido training, I see it works well with many other styles training providing openings for other techniques, which I call my old friends from other schools of training.
So, not to rely on what works is foolish. But learning to make other things work within Aikido? You decide.
How long did it take to begin to understand Aikido, and will you or I ever Master IT?
Probably not, but practicing is a lot of fun!
