Only had time to listen to about 30 minutes of it, enough to know we share a similar view.
I too when using the word God, do not mean what most people do; but rather feel that what the word G-O-D points to is not a personal deity, or anything which is circumscribable; but rather That which all existence flows from, is sustained by, and foundationally is.
Einstein, it seems felt that "God" could be mathematically defined in such a way as to be predictable, and so was extremely flippant when Quantum Physicists discovered chaos and stark unpredictability at the atomic level. To this he gave his famous reply "God does not play dice". I don't hold to such a restrictive view; but rather feel that even to God, God is a mystery and wonder, so that the next moment is always a surprise.
