When "I am not," the Overself is. When the universe is, God is not. If the Overself did not hide itself, the ego could not come forth. If God were everywhere apparent, there would be no universe. In that deep underground mining operation which is the dark night of the soul, the saint's spirituality is utterly lost from sight, feeling, and consciousness. He is left for a while bereft of all that he has gained, while what remains of his ego is relentlessly crushed. Yet this is followed by a true and lasting enlightenment!
