Nirvana may be the utmost and fundamental, but without a consciousness it is hard to call it a deity. It saddens me a bit, because Eastern religions (Buddhism more than any other) are great advocates against the destructive effects of pride, but in subordinating all humanity to the God in Whom "we live and move and have our being" (Bible Gateway helpfully notes Paul was quoting Epimenides there ) they sacrifice His personality along with ours. Forms and Ideals can find no purchase in that environment, but there IS "an 'I' in 'team,'" without which the admirable holism loses all value and meaning.
