Some of this sounds like the concept of mushin. Do you see them being inter related or as someting different?
They are definitely related - the mind needs to be calm and clear for aiki to freely express itself through you. I think a different way to say this is that if you stay relaxed and centered you can operate as one with your intuitive faculties, and the proper technique will flow from you.
If you watched somebody in this state it would look a lot like a crazy old man demonstrating techniques from an apparently vast syllabus.
(So I gather, anyway....)
