Another book about religion and mental health: The Awakened Brain. Or, as the author, Lisa Miller, prefers to put it, “The Psychology of Spirituality and Our Search for Meaning”. It’s by a psychologist who has spent years working on the association between the two.

Her book starts in breathless form in 2012 when she and her team at Columbia University first look at MRI scans from patients with a high and low genetic risk of depression – because this, like so much else, has an hereditary component. But respondents were also asked whether religion and spirituality were important to them.

You know what’s coming, don’t you? The results made the sceptical team fall silent (it’s that kind of book). “The high-spiritual brain was healthier and more robust than the non-spiritual brain. And the high-spiritual brain was thicker and stronger in exactly the same regions that weaken and wither in depressed brains.”
