It's not You, It's Me
So we have an emerging concept of aiki, derived from strong internal power. There are a several major models out there and gaining some exposure. There are some differences of opinion about the details, even among the major proponents of the internal power models.
Clearly the aiki models contain elements that create a strong response, such a strong response as to craft perceptions within people who have yet to experience one or more training models. So what are the specific elements that you feel affect the validity of the model(s)? What would change your opinion? Are these measures of validity consistent with your exposure to other training models within Aikido?
For example, a previous comment made about all of the aiki models was, "how does it help me fight bad guys?" You could elaborate on this statement by identifying the specific model of aiki with which your exposure does not satisfactorily give you confidence to apply the model in applied waza.
Or, maybe the Chinese influence in some models is not consistent with your Japanese martial art. What model was too culturally difficult to translate into your training? Or, maybe there is no translation yet and you are not comfortable leaving aikido to get the information.
Or, maybe you believe its BS. What model were you exposed to that felt fake or contrived? Were you constantly being told how to attack or move in a manner not consistent with your fighting experience or training?
Or, maybe you don't yet have exposure to the various aiki models. What is your perception of the training? Why does it interest you enough to participate in discussion about it?
What's your story? I am really looking at discussing the bolded questions, but it is possible your own story is similar to one of the examples.
