I am continually amazed by the number of people for whom it is not enough for aikido to simply be aikido. Aikido is not for explaining the origin of life and matter -- we have science for that.
No need to bury this comment in a bottle in your back yard - I think this is one of the most sensible comments on this thread.
For the record I have been studying Aikido since 1957 - not the occasional week end course - but at length with the likes of Kenshiro Abbe Sensei - Nakazono Sensei - Noro Sensei - Assistant to TK Chiba Sensei.
