Materialist neuroscientists have not succeeded in providing a satisfactory neurobiological theory of how mind, consciousness, self, and religious/spiritual/mystical experiences arise from the interaction between various brain regions, neural circuits and neurotransmitters.
According to Beauregard (2007), this enterprise is doomed to failure. Why? Because of the immense epistemological gap between the psychological realm (psyche) and the physical realm (physis)….By virtue of this cardinal difference psyche cannot be reduced to physis. Nevertheless, psyche and physis represent complementary aspects of the same underlying principle; neither can be entirely discounted in favor of the other.
The findings of near death experiencers suggest that the mind and consciousness can continue when clinical criteria of death have been reached and the brain no longer functions…Such findings lead Beauregard (2007) to point that the transformative power of religious/spiritual/mystical experiences arises from and encounter with an objectively real spiritual force that exists independently from the individuals who have the experience.
This conclusion is compatible with the hypothesis that the brain does not generate but transmits and expresses mental processes/events.
