There is no separation.
Thinking to blend and how to "make an aiki connection" and concentrating on THEM... is everything that is wrong with aikido. It's full speed...in the wrong direction.
Which is why I voted Ki.
What you are saying put in other words is pretty much what Tohei Sensei has been saying for nearly 50 years.
Aiki is an aspect of the phenomena labeled Ki.
Developing Ki really means exercises for developing your attention/awareness to the natural principles of your mind and body being inseparable and exploiting that.
