What research has been done to inspect whether there are connections between the spiritual and the physical?
Starting from the belief that spiritual does in fact exist, has there been any research done to discover what sort of provable effects and connections exist between the physical and/or mental aspects of human life? If so, what do they present? Are their any TED talks directed towards this?
I assume those interested would be those who study and are interested in the overlap of various studies such has cultural, medical, religious, and psychological, and their practical relationships. Potential experts this question is geared to are those in the field such as neuroscientists, psychologists, endocrinologist, physicians, religious workers, etc...
There of course is a starting bias that the spiritual does in fact exist, and in definition is different that the psychological, emotional, and physical.
