Ah well, leprechauns deserve a thread of their own, bless 'em.
The early Christian mystics spent a lot of time trying to understand the nature of God, or what God is, and then came up with a conclusion that the way to gain insight is to abandon all previous ideas, ego and stop striving but surrender to the notion that God is unknowable. Then insights into the nature of God will happen.
I daresay that involves a lot of meditation, something I've never been able to do effectively. I day dream and my mind wanders. Very pleasant but not meditation, indeed I will have left the original subject far behind. So, like Alan, I will be content to not understand God.
