I was just reading your post in the Aikido thread & you mentioned OSensei. Is this Ueshiba? And if it is, what’s the story with the “OSensei” as opposed to “Sensei”? I’ve heard Aikido people use the term before & I’m just curious. 
doesn’t it mean grand or supreme teacher or something?
Yes it means teacher’s teacher or grand teacher in japanese.
