I avoid saying God because people already have a concept of God framed in their minds-- a point of light or consciousness that controls everything. But that is a short-sighted view of God, definitely not what I am referring to. A centralized entity contradicts omnipresence. Therefore, I used to say the divine. Consider how people conceptualize the divine-- expansive, infinite, spiritual, and ecstatic. One day I realised it, too, wasn't what I wanted to say.
The image evoked by the word "divine" is itself limited by the concept of it, which I myself introduced when I said it. By saying the word "divine", I created the same trap I wanted to evade by not saying "God". I still ended up conveying a concept or "an image of God". But the moment you form an image, it is no longer what I talking of.
"Don't make images of God." Ever heard that one? The act of making invokes "a maker", which is the self(ego) here. It becomes your God, your invention, not the God. However, truth is not an invention, but a discovery.
See, when you give up all knowledge and all concepts of God, you might have a realization, but you can't say it, for saying it requires putting it into a concept or an image. "Those who know don't speak. Those who speak don't know." Ever heard that one? Look it up.
