No, it does not. Did you miss that part of my post in which I told you I actually work in a place where mentally and emotionally challenged people are treated? This psychology thing that you keep talking about? I live in one of the most religious states in the US, and we have quite a heavy caseload of devout (mostly) christians. Religion does NOT keep one sane. It didn't keep Andrea Yates sane when she drowned her 5 kids in the bathtub because god told her to. But you know what DOES help people with Post Partum Psychosis? Psychotropic medications, developed from science.
Religion can be comforting to some. But it's not a cure, and considering the high number of people on antdepressants, it's only marginal at comforting. Then there's this:
"Prayers offered by strangers had no effect on the recovery of people who were undergoing heart surgery, a large and long-awaited study has found.
And patients who knew they were being prayed for had a higher rate of post-operative complications like abnormal heart rhythms, perhaps because of the expectations the prayers created, the researchers suggested."

You start off talking about a more meditative style of prayer that
can be beneficial to people and then try to assign healing powers to prayer that just aren't justified. Positive thinking
is a thing, but that has as much to do with how the chemistry in the brain is being rearranged (it is absolutely true that negativity breeds negativity), but prayer simply doesn't have the type of medicinal powers you continue to ascribe to it.
