Do you object when other people here say that what they are doing is "Aiki"?
this strikes me as a bit ironic...to be fair, isn't this usually what "The IP Crowd" (for lack of a better description) tends to do? And, apart from styles in communication perhaps, isn't this probably the main source of contention we see in these conversations? I know I tend to have a problem with speed reading on AikiWeb (and thus missing crucial bits), and so I apologize if this is another case of that, but from my incomplete vantage, this is central to the difficulties we see; more so than suggestions of profiteering (which I think are fairly easily shown to be false).
That excludes Iwama, Yoshinkan and Tomiki lineages. Are you saying that they did retain the old goods?
I find it hard to believe Tomiki Sensei didn't transmit his understanding of aiki, but based on what I've managed to read, "the goods" do take several years to really develop. Not that it cannot be developed within a few years, but to be "good" (whatever that means) it takes considerable effort...a huge change in day-to-day use of the body, which I assume (and maybe you know what "they" say about assume-ing) most people aren't willing to adopt.
...thinking of the notion that this aspect of Aikido training is somewhat self-selecting (i.e. it takes a degree of commitment that is easy to miss).
