An analogy: brain is the river bed and thought is the stream flowing through it -- the thought is constrained by the river bed, but thought can alter the river bed as well.

"Eventually, all things merge into one, and a river runs through it. The river was cut by the world's great flood and runs over rocks from the basement of time. On some of those rocks are timeless raindrops. Under the rocks are the words, and some of the words are theirs. I am haunted by waters."
