Is God a real person or entity or simply a chemical reaction in the brain? A recent article in Scientific American called Searching for God in the Brain discusses some interesting observations on this topic. Studies done on various people who are at certain stages of spirituality (including nuns) allows us to observe brain activity that appears to be related to religious experiences. Does this disprove the existence of God or strengthen your testimony? Are these centers of brain activity simply physical-world receptors to equivalent activity on the spiritual plane?
