I know of two times when Ueshiba was at his peak that he was defeated - there may be others. The one I am not at liberty to say - but there is no doubt.
Also the time when faced by the professional hunter .. not actually defeated but backed down as it was obvious the shot would hit home. Dodging not an option or there would be no need to back down.
Inspirational, yes, but deification is not required. Self delusion even gets the best of them. We are our own worst enemy-sometimes.
