Imagine for a moment you're driving home from work, and that you've just come from having a pretty rough day. As you drive along, your eyes see the road before you, but your mind is in the past. It's very busy re-running all of the day's unpleasant events.
Over and over again, you feel that painful stab of some thoughtless remark someone cruelly blurted out, or the embarrassment of that stupid comment you made without thinking. And with each mental replay of this unpleasant scene, you go deeper and deeper into thought, desperately trying to find a way to escape what seems an intolerable situation.
But what you don't see happening to you is that the more you think, the more you sink! Exactly the opposite of what you think you're accomplishing. And the deeper you sink in thought, the less you're able to see what the rest of you is doing.
Driving recklessly, speeding, missing the exit you want -- these, and other equally dangerous stunts, are only a few of the foolish things that happen to you while driving under the influence of a stream of self-compromising, self-wrecking thoughts.
Your life, in moments such as these, is actually out of your hands. It belongs to your thinking, to an undeveloped nature that doesn't understand what it's doing to itself, or to you, as it struggles to find a way out from under the weight of its own unconscious actions.
