Ueshiba giving secret massages now? How significant can you get?
I think the statement of hidden in plain sight has gone into cuckoo land.
Maybe he was a mason from the yin yang order.
They are not secret, Graham, they're obvious, widespread and known. Your founder decided to talk about some known concepts in plain language... that got mistranslated.
His biographers and translators didn't get it.
He told them they didn't get it,
They admitted they didn't get it,
And several of them admit they just wanted him to shut up!
And no one I know of has said no one in aikido gets it.
