The word certainly has lots of meanings since it applies to the greatest mysteries, and there are many competing solutions to them. My point is that the more rigorous, coherent, esoteric meaning that emerges from an understanding of religion's purpose and history posits something like this humbling, mystical pantheism. Other mystics identify God with consciousness, but that strikes me as too anthropocentric, or at least too life-centric. The more mysterious or "transcendent" God is, the more inhuman the deity must be, which means consciousness needn't be central to its identity. It's central to ours, but we're not central to God or to the universe.
