If you are okay, it doesn't matter how weak you are, you're still okay. It doesn't matter if anyone takes from you, or beats you, you're okay. It's not about your ability to influence others with your "power" it's about being able to accept, with great joy, any path that your life may take.
So I don't believe it's about "fear of power", it's about understanding that power was never the real goal. Easily said, but I'm sure not there yet.
All well and good for the individual human, but not to apply to the art that came down from Ueshiba. Aikido is powerful and much of its grace comes from its power. Those who denigrate power out-and-out, then try to neuter aikido by teaching that it should have no power...to be kind, they're on a seriously mistaken path.
