Does religion help cure insanity?

I get pa­pers cited at me, (the first is about “re­li­gion and spiritu­al­ity”, the rest about spe­cific med­i­ta­tion dis­ci­plines) about but I can’t tell whether they’re well-done or not. I be­lieve LessWrong is the ideal place to ask about this be­cause there’s a healthy com­bi­na­tion of in­ter­est for self-im­prove­ment tech­niques and solid skep­ti­cism against quack­ery. I thought it would be a solid enough topic to merit its own thread rather than a dis­cus­sion in Open Thread.
