It is understandable that people would want to prove the existence of God in a rational way, and I myself think that reason should be utilized in this metaphysical endeavor.

There is obviously a deep emotional connection to God and divinity when you pray, for example, or do other various rituals praising God. Even in intellectual pursuits of God, there is an emotional moment of "eureka" when you find a revelation from contemplating metaphysical problems and conceptualization.

When Baime meditated in Newberg's brain scanner, his brain mirrored those feelings. As expected, his frontal lobes lit up on the screen: Meditation is sheer concentration, after all. But what fascinated Newberg was that Baime's parietal lobes went dark.
When further looking into the effects on prayer, the positive benefits would include lower rates of depression, addiction, and divorce, which was the results from a study done at the Virginia Commonwealth University.

Concluding this short treatise, there is an emotional aspect of spirituality and God that cannot simply be measured, or made sense of, by simple empirical science or an analytical mind. In going beyond this paradigm, it is possible that we can further comprehend reality expansively as part of a curiosity of making sense of the Universe.
