First, I'd like to say I don't like to see A´kido as a way to re-establish harmony. I prefer to see it as a way to maintain balance.
Rather than blocking uke's strikes in order to control him (you're kinky sex addicted, aren't you ?), why not guiding his fists in a way you prefer, to feel his Ki, to "swallow" his strength, etc. ?!
I think that, if you begin to block, you do play his game. When two torrents meet, what does happen, then ? It makes a more powerful torrent
(with also many splashes
, but it's another part of the story
Instead, what does happen when a torrent meet a peaceful lake ? It's simply absorbed by the lake and nothing happens. The torrent keeps flowing out, the lake is still peaceful and life goes on !!
Moreover, why imagining someone hits you ? Are you parano´d, or what
? I think we must be prepared (I should say awared). If you're afraid of being hurt, you'll act in order not to be hurt. I don't think I would be happy if you immobilize me because I begin scratching my head too quickly for you
If you are so nervous, you ought to get an eye on one of that site's articles (especially those speaking about calmness)...
