Does anyone know the source document if this analogy used by Harvard theologian Diana Eck? The analogy in question is where she compares spiritual development to rising higher on a mountain. When you get up above the cloud level and look around, you begin to notice that others at that level all begin to look the same as you, i.e. those of all religions are the same. I would like to find the book in which she wrote that without having to read all her books. Can you help?
