I respect your opinion, but I think the worst thing to do for any martial artist is to try to understand techniques cerebrally.
I repsect your opinion but as much as I have seen people learn Aikido the ones who advance the fastest are the ones who learn through their body but also try to understand what the body does.
I'm one of those who thinks that Aikido cannot be taught - it can only be learned. But sometimes a simple abstract guiding sentence or metaphor as "show me your palms" or "stand where I do not" can give such a huge push for someone who is trying to learn.
One's mind has to know what the body is doing and vice versa. That's harmony.
