Unless you’re drunk, it’s easy to walk straight. But when you’re blindfolded, or when you have no visual point of reference like the sun or a mountaintop, something funny happens: although you think you’re walking straight, you are doomed to walk in circles. And so a blindfold is a nice metaphor for unawareness. Being unaware may lead you to believe you’re walking straight, going from A to B, while in fact you’re going in (the same) circles over and over. Being aware is like putting the blindfold off, giving you the ability to really see where you’re going and to make conscious choices accordingly.
