I think this whole focus on Ueshiba and what he taught when and what he truly-o.... ooley-o... meant to say, and what X sensei said about Y's approach based on his training 6 years prior to the sun setting to the east of mount Budoo.......is poodo.

If you just HAVE to focus on Ueshiba then trust in what he did.
Develope internal strength and power. Go down his path. Dare to storm the walls and believe you can gain power. Then decide just what effects it is having on ...you... and where your ethics lie.
There are plenty of guys who train in these things.
I think all is still right in the world.
