[she used to say that] each of us has a veil between ourselves and the rest of the world – like a bride wears on her wedding day—except this kind of veil is invisible. we walk around happily with these invisible veils hanging down over our faces. the world is kind of blurry. we like it that way. but sometimes our veils are pushed away for a few moments – like there’s a wind blowing it from our faces – and when the veil lifts, we can see the world as it really is, just for those few seconds before it settles down again. we see all the beauty and cruelty and sadness and love, but mostly we are happy not to. some people learn to lift the veils themselves. then they don’t have to depend on the wind anymore. ...it’s just her way of saying that most of the time people get distracted by little stuff, and ignore the big stuff.
