Here’s what I don’t get about an experience like Bob Jesse’s: Why in the world would you ever credit it at all? I didn’t understand why you wouldn’t simply file it under “interesting dream” or “drug-induced fantasy.” But along with the feeling of ineffability, the conviction that some profound objective truth has been disclosed to you is a hallmark of the mystical experience, regardless of whether it has been occasioned by a drug, meditation, fasting, flagellation, or sensory deprivation.
