Re: How do Akikai Aikido students learn about KI?
Not really in the Aikikai myself anymore, but have been for 15 odd years or so.
I have never done specific techniques to enhance KI. Like Carsten says it is trained/polished within the techniques. This is I think where O Sensei and Tohei differed in opinion. Ueshiba said KI is integral part of Aikido, one should not (try to) separate it. Tohei's approach was to have some practise focused on KI development in order to improve your techniques.
My teacher always says there is nothing cosmic about Aikido, just practise, practise and practise, but off course properly.
I tend to interpret the question like:
how do Aikikai students learn about kino nagare?
how do Aikikai students learn about ma ai?
how do Aikikai students learn about kimusubi?
how do Aikikai students learn about shi sei?
There is no emphasis on either aspect, at least in my experience.
