What if in reality there is no God; that despite our spiritual beliefs and practices we discover that they are no more than mental concepts that somehow comfort us as human beings? What if peace and stillness are merely the result of the sophisticated inner workings of the brain? Are God and the brain the same? At the end of the day, the answer to that question may not even matter, but actually facing the core of our doubt might be the most important thing we ever do. Where is God? Where is stillness? What is true?
