Richard Bach, the author of Johnathan Livingston Seagull, also wrote a book called Illusions. In it, the character who is seeking answers to some of life's questions is travelling with a professional barnstormer. The barnstormer is a kind of guru who tries to help him answer his questions. He tells the seeker that he can have anything he wants from the universe, he just has to ask for it. The seeker doesn't believe this, so the messiah asks him to test it with something simple.
"Okay," says the seeker, "a blue feather." He looks around and the messiah tells him he'll find it soon. The next day, or maybe a few days later, they're in another town eating breakfast and the seeker is thunderstruck to see a picture of a blue feather on the side of the milk carton. It's from the "Blue Feather Dairy."
He's astonished and points it out to the messiah who just says "I thought you wanted an actual feather."
I think of this story every time I find a blue feather. I found one today on the grass next to the apron, right where I was about to lower the stairs. The hardest part may not be getting what you want, but figuring out what it is that you really want.
