The meditation is to train me to listen to it, above all the other noise of life. If someone really was coming up behind me with a machete, it would try to warn me, and if I'd trained enough, I'd be able to hear it.

[It's obviously more complex than he's making it out to be, and even now he wonders if he's underselling the principles. But it's a learning experience, so he'll do his best and try to be patient.]
