No, Amos...on the level at which he is saying that statement, St. Augustine is absolutely correct. God cannot be understood with the mind, because what is finite (you or me) cannot understand what is limitless. We can talk about it, we can talk all around it, we can intellectualize it as a concept, but we cannot understand it.

You can, however, BE it. And I have heard that that is really something, to put it mildly...after that happens, all bets are off. You don't have to understand anymore, once you ARE.
