An FBvian clears all this up:
Visualize the confluence of many streams & rivers as they flow into a vast ocean…and each flows with its own channel. The core of this mighty confluence of streams & rivers is the massive power which directs and creates its course.
Now, ‘way, ‘way off to the far side there flows a little bitty stream with its own main channel….which to my way of thinking, is still ‘way far away from the main stream of all the other rivers.
Me, I’m channeling Mark Twain.
