From Chapter 19 of A Thousand Names for Joy by Byron Katie:

... There's no mistake in the universe. It's not possible to have the concept "mistake" unless you're comparing what is with what isn't. Without the story in your mind, it's all perfect. No mistake. Strangers used to hear about me and show up at my front door (this was in 1986), and some of them would put their palms together and bow and say, "Namaste." I had never heard that before—people don't say "Namaste" in Barstow, the little desert town where I lived. So I thought they were saying, "No mistake." I was thrilled that the people coming to my door were so wise. "No mistake. No mistake."
