For many skeptics, the concept of spirituality is easily dismissed as mystical or irrational, often conflated with supernatural beliefs or religious dogma. I understand this perspective deeply because, at times in my own personal development, I struggled to reconcile my own profound spiritual experiences with a scientific view of the world. For a long period of my life, I viewed my spiritual impulses as a tendency toward delusion or wishful thinking—a quirk of neurology to be mitigated rather than embraced. I found that position deeply unsatisfying, however, and (like any skeptic might) I felt relentlessly compelled to explore its underpinnings.
