Picked up a book in the dojo where my Chinese Medicine practice is, 'The Secrets of Aikido'. As far as I could tell the secrets are that for all his martial talents, Ueshiba was just a bit insane; and that if what he was doing was aikido, then nobody else has ever done aikido. Anyway the book has a chapter titled shugyo - constant training. There are no secrets to butokuryu aikijujutsu, there's just constant training. So happy Australia/ Invasion day, we train as usual.
