What are near-death experiences, out-of-body sensations, and spiritual ecstasy? And what do they have in common? Perhaps no one is more qualified to answer these questions than renowned neurobiologist Dr. Kevin Nelson. Drawing on his more than three decades of groundbreaking research into the "borderlands of consciousness," Dr. Nelson offers an unprecedented journey into the site of spiritual experience: the brain. Filled with amazing firsthand accounts as varied as a patient seeing the devil battling with his guardian angel to a man watching the universe synchronize around a pinball machine, The Spiritual Doorway in the Brain is an eloquent examination of our brains' spiritual "hardwiring" that will enthrall believers and skeptics alike.
