In religious studies, the feeling of finding yourself in a divine presence is called experiencing the numen. Monte Python would explain this feeling as one's apprehension of the vastness of the universe and our small place within it:
Humanities and British humor aside, what does neuroscience say about the numen? Studies confirm several observations:
1) There is no single god spot in the brain.
2) The feeling of the numen can be induced through manipulation of one's brain ... (skip to 1:20).
3) The induction of the numen through manipulation shows only the locus of the feeling, not level of religiosity.
Given this locus of numenous perception, however, would it not be more parsimonious to attribute such a feeling in your life to a triggering of this locus rather than actual contact with the divine?
