Book excerpt: The “spiritual but not religious” are the fastest-growing denomination on America today. Yet what are the roadmaps? What does the spiritual search look like for a seeker in 21st century America, fully plugged-in, online, cynical, and sincere? Enlightenment by Trial and Error is a unique book by bestselling author and Daily Beast columnist Jay Michaelson. Today, Michaelson is a rabbi with a PhD in Jewish Thought, a teacher on the Ten Percent Happier meditation app, and a political columnist read by a quarter million readers per month. But not long ago, Jay was a young spiritual seeker, pursuing mystical experiences (and even enlightenment) with an open heart and restless intellectual curiosity. Drawn from essays written over a ten-year period of questioning and exploration, this book is a unique record of the spiritual search, from the perspective of someone who made plenty of mistakes along the way.
