So meditation is not really mind-effort. Real meditation is not effort at all. Real meditation is just allowing the mind to have its own way, and not interfering in any way whatsoever - just remaining watchful, witnessing. It silences, by and by, it becomes still. One day it is gone. You are left alone.
When I interviewed Paul Bremer in his office he had almost no books on his shelves. He had a couple of management books, like "Leadership" by Rudolph Giuliani. I didn't take it as an encouraging sign.
