"When subjects engaged in meditation or prayer, for example, their ability to concentrate increased dramatically. Brain scans often revealed an intense loss of one's sense of self during such exercises."
"When subjects spoke in tongues, the activity of their frontal lobes -- the largest and most complex region of the brain -- dropped rather than increased. Newberg interprets this finding as evidence that the subjects aren't speaking in tongues of their own volition, but rather allowing it to happen to them."
"Our studies are starting to show that we can fundamentally change the brain through religious experience."
