First of all, I will point out that "Omote" and "Ura" have several interpretations in the Aikido world. You can google them as well as I can. In the interest of "full disclosure," in fact, I'll admit that I think the way we teach Omote and Ura at the Roanoke Budo Kai is not my favorite. I'll explain.
In my past (admittedly limited) experience, but backed up by most of what I find on the internet, Omote usually means something like "to Uke's front side," or "to the front of Uke's center line." Ura usually means "behind Uke," or "to the rear of Uke's center line." Sometimes they even just mean "the standard technique" and "the alternate version."
For us at the Kai, Omote and Ura mean something slightly different, and very specific: Omote means "forward (relative to Nage's original position)," and Ura means "backward (relative to Nage's original position)."
Once more, with feeling... At the Kai, Omote and Ura are statically defined cardinal directions, relative to the original position of Uke and Nage. In my past experience, they were dynamically defined descriptions of a relationship between Uke and Nage throughout the technique.
As with most things in life, both viewpoints have merit. In this case it's a little like "east and west" versus "left and right." If you're trying to find the restaurant, directions that say "head south on Interstate 81" can be more useful that "turn left on Interstate 81." Of course, if you're on Hershberger Road, "turn right onto Williamson Road" is probably more useful than "turn southeast."
Treating Omote and Ura as cardinal directions in our dojo seems to add an element of precision to the training. If you know exactly which direction you're supposed to end up moving, you can work toward that goal with purpose. Precision is one of the hallmarks of our training at the Kai. Also, I think a lot of our techniques are quite linear compared to other styles, and I think the cardinal directions definitions suit that style well.
On the other hand, I think treating Omote and Ura as relative directions puts the focus on the relationship between Uke and Nage, which I think is the key no matter what "style" you're training in. And therein lies the root of my little revelation on Thursday.
Tonya pointed out the "simple" fact that, during Kosetori Ikkyo Ura, after you've taken Uke's balance, it's not about "pulling" Uke around to the Ura direction or somehow "reversing Uke's momentum" (as I pictured it) -- it's about changing YOUR direction -- as NAGE. Once I grokked that, what Uke was doing (in my control, of course), was almost irrelevant. Oh yeah -- this is Aikido. Duh.
So, for me, this was yet another case of an "Aha!" moment that I apparently wasn't ready to hear the other 10,000 times I'd heard that particular teaching. Changing my direction (as Nage) from one wall to the opposite wall made our definition of "Ura" quite obvious, and, in my case, psychologically painless. I believe I've finally come to terms with the cardinal directions.
