Great analogy!
I like what Ekhart Tolle said in 'The Power of Now".
"The word God has become empty of meaning through thousands of years of misuse. I use it sometimes, but I do so sparingly. By misuse, I mean that people who have never even glimpsed the realm of the sacred, the infinite vastness behind that word, use it with great conviction, as if they knew what they are talking about. Or they argue against it, as if they knew what it is that they are denying."
