“We have found a neuropsychological basis for spirituality, but it’s not isolated to one specific area of the brain,” said Brick Johnstone, professor of health psychology in the School of Health Professions. “Spirituality is a much more dynamic concept that uses many parts of the brain. Certain parts of the brain play more predominant roles, but they all work together to facilitate individuals’ spiritual experiences.”
Is it any wonder that most cultures use music and sometimes dance to induce "spiritual" experiences? The Huffpo piece mentions "meditation" which is actually less common around the world than music and dance as a tool. Could the black church in America and other African-influenced religious practices survive without music? Is it any accident that Rick Warren has a "praise band" and evangelicals use Christian rock to keep the young'uns in line?
Now I have only one more question: would Jesus play a Fender or a Gibson?
