I’ve no reason to doubt the self reports of so many who claim that these meditation practices helped them; and when a rational, skeptical person like Sam Harris describes them as improving the functioning of the mind, it’s intriguing. But I still have severe doubts about some of these claims, because I wonder where the beef is. If, as Harris suggests, over time the practice gives you a kind of mental superpower, where are the mathematicians who ascribe their solution of a long-unsolved problem to meditation? Where is the evidence that meditation actually improves the functioning of the mind, aside from making its practitioners feel better? (The latter is valuable, but it’s different from the implied claim that I‘m skeptical about.)
