> It seems a little disingenuous to say that there is no definition of God.
There's no useful definition. Defining something as being 'metaphysically ultimate' doesn't describe any of its properties.
> What was the definition of oxygen before it was discovered? How about dark matter?
Both oxygen and dark matter were hypothesised based on observations. The definitions suggested by those hypotheses were then tested (dark matter still hasn't been discovered).
Through what experiment are you intending to discover God?
> Krishna explains that God can be known through meditation.
Define "known" in a way that bridges that context and this discussion and I'll buy you a Porsche.
> It's completely reasonable and logical to debate revealed knowledge.
No, sorry, revelation is faith, not knowledge. 'Revealed knowledge' is an oxymoron.
