Ogi, in and of itself doesn't mean "hidden" or "secret". Indeed, that's why Daito-ryu's densho refer to hiden ogi, with hiden "・` carrying the meaning of "secret".
Yes, there is a lengthy explanation on pp.21-23 of Stanley Pranin's edition of Budo
, together with a copy of the inside back cover of Mitsunosuke Akazawa's copy.
On Page 40 of the Budo
manual are douka
entitled Budo Ogi (Ka)
. The first one is about SEI (makoto) being the key to realising the oneness of KEN 顕 and YU 幽.
