Re: Ki is Kindness.
Speculating a bit further, ki then is present and being expressed both in the "purified" and "unpurified" mind. "Misogi" (programmatically) is supposed to change the characteristics of that flow.
Aikido-as-misogi takes aim at "making better people."
The question posed by this thread is whether the two can exist apart from one another.
For one who also insists that aikido must be budo, an equally pertinent question may be whether the two can exist together, without either having its essential character subsumed by the combination.
Like an old married couple.
