Mister God... is empty

Here's one analogy from Mister God that I need time to digest and live.

(p. 43) ... God is empty... (discussion preceding this conversation is that of object getting their colour - by absorbing all the colours except the one that we see it as its own colour - but that is exactly the colour which is not its own!)

A flower that didn't want the yellow light was called yellow by us because that is what we saw. You shouldn't say the same thing about Mister God. Mister God wanted everything, so he didn't reflect anything back! Now if Mister God didn't reflect anything back, we couldn't possibly see him, could we? So as far as we are concerned,so far as we were able to understand what Mister god was, we simply had to admit that Mister god was quite empty. Not empty because there was truly nothing there, but empty because he accepted everything, because he wanted everything and did not reflect anything back!

This is what we were being asked to do, throw away our pieces of colored glass and see clearly.
