In other words, is there a meta-review on meditation research? (Then we should ask Scott Alexander to review it.)
Not sure whether that’s what you’re looking for, but I like the Wikipedia pages on effects of meditation, brain activity and meditation, meditation and pain and mechanisms of mindfulness meditation (clearly just a starting point, but asking for a literature review for research on meditation sounds like asking for a literature review on the research on foreign aid—nearly impossible to do both exhaustive and in-depth, just because of the sheer scope of the field).
